Vocative case

However, recent literature contains lively debate about the extent to which such vocative suffixes share crucial properties with prototypical case; see Maché (2025) for an extensive discussion.

Typically, case is assigned by verbs, prepositions, nouns, or adjectives to their complements. In the case of vocatives, this is less straightforward, since there is no phonologically realised assigner. Moreover, some languages, including Bulgarian, have lost all overt realisation of case assigned by verbs and prepositions while retaining vocative suffixes. In many other languages, the realisation of vocatives may differ substantially from that of the remaining cases. Although the large majority of case languages realise case through suffixation, many of these languages mark vocatives by other morphological means, such as truncation, stress shift, or intonational marking, for instance the new Russian vocative or prenominal vocative particles in Arabic. Finally, vocative suffixes are notoriously difficult to distinguish from other forms of realisations such as vocative particles that occur as clitics that follow the noun such as in many African languages.

Some recent theories subscribing to Ross' performative hypothesis however maintain that vocative is a case in the narrow sense which is assigned by a phonologically empty speech act predicate such as Hill.

A noun of address is an expression of direct address by which the identity of the party spoken to is set forth expressly within a sentence. For example, in the sentence "I don't know, John," John is a noun of address that indicates the party being addressed, as opposed to the sentence "I don't know John", in which "John" is the direct object of the verb "know".

As observed by Zwicky, vocative case is used to express at least two functions: (i) as a call aimed to attract the attention of an unratified overhearer, as (ii) address to maintain and perform the social relation towards the hearer.

Some authors including Gutzmann assume that so-called expressive vocatives are further distinct vocative function.

Historically, the vocative case was an element of the Indo-European case system and existed in Latin, Sanskrit, and Ancient Greek. In many modern Indo-European languages (English, Spanish, etc.) the vocative case has been absorbed by the nominative, but others still distinguish it, including the Baltic languages, some Celtic languages, Modern Greek and most Slavic languages. Some linguists, such as Albert Thumb, argue that the vocative form originated as the bare form of a noun when it does not belong to any case, and that its vocative role came about because nouns of address do not play a syntactic role in relation to other words in sentences; since case suffixes mark these syntactic roles, one was not required. Pronouns usually lack vocative forms.

Indo-European languages

Comparison

Distinct vocative forms are assumed to have existed in all early Indo-European languages and survive in some. Here is, for example, the Indo-European word for "wolf" in various languages:

The elements separated with hyphens denote the stem, the so-called thematic vowel of the case and the actual suffix. In Latin, for example, the nominative case is lupus and the vocative case is lupe, but the accusative case is lupum. The asterisks before the Proto-Indo-European words means that they are theoretical reconstructions and are not attested in a written source. The symbol ◌̩ (vertical line below) indicates a consonant serving as a vowel. All final consonants were lost in Proto-Slavic, so both the nominative and vocative Old Church Slavonic forms do not have true endings, only reflexes of the old thematic vowels.

Vocative singulars in Slavic languages appear to be irregular as a consequence of the Slavic first palatalization, which caused *k, *g and *x, when followed by an *e (as in the vocative suffix), to become č, ž, and š, respectively. Some modern Slavic languages have replaced these forms with a more regular vocative ending, so for example in Czech the usual masculine animate vocative is -e, except for roots ending in velar consonants, where it is now usually -u (e.g. chlap > chlape, but vlk > vlku). This is an instance of the paradigmatic complexity introduced into Slavic by successive waves of palatalisation, with some languages retaining more complex or irregular paradigms (such as Czech), and others tending towards simplification and regularization (such as Russian, which has lost the vocative as a productive case entirely).

Baltic languages

Lithuanian

The vocative is distinct in singular and identical to the nominative in the plural, for all inflected nouns. Nouns with a nominative singular ending in -a have a vocative singular usually identically written but distinct in accentuation.

In Lithuanian, the form that a given noun takes depends on its declension class and, sometimes, on its gender. There have been several changes in history, the last being the -ai ending formed between the 18th and 19th centuries. The older forms are listed under "other forms".

Some nouns of the e- and a- stems declensions (both proper ones and not) are stressed differently: "aikštė": "aikšte!" (square); "tauta": "tauta!". In addition, nouns of e-stems have an ablaut of long vowel ė in nominative and short vowel e in vocative. In pronunciation, ė is close-mid vowel , and e is open-mid vowel .

The vocative of diminutive nouns with the suffix -(i)ukas most frequently has no ending: broliùk "brother!", etc. A less frequent alternative is the ending -ai, which is also slightly dialectal: broliùkai, etc.

Colloquially, some personal names with a masculine -(i)(j)o stem and diminutives with the suffixes -elis, -ėlis have an alternative vocative singular form characterized by a zero ending (i.e. the stem alone acts as the voc. sg.): Adõm "Adam!" in addition to Adõmai, Mýkol "Michael!" in addition to Mýkolai, vaikẽl "kid!" in addition to vaikẽli, etc.

Celtic languages

Goidelic languages

Irish

The vocative case in Irish operates in a similar fashion to Scottish Gaelic. The principal marker is the vocative particle a, which causes lenition of the following initial letter.

In the singular there is no special form, except for first declension nouns. These are masculine nouns that end in a broad (non-palatal) consonant, which is made slender (palatal) to build the singular vocative (as well as the singular genitive and plural nominative). Adjectives are also lenited. In many cases this means that (in the singular) masculine vocatives resemble the genitive and feminine vocatives resemble the nominative.

The vocative plural is usually the same as the nominative plural except, again, for first declension nouns. In the standard language first declension nouns show the vocative plural by adding -a. In the spoken dialects, the vocative plural often has the same form as the nominative plural (as with the nouns of other declensions) or the dative plural (e.g. A fhearaibh! = Men!).

Scottish Gaelic

The vocative case in Scottish Gaelic follows the same basic pattern as Irish. The vocative case causes lenition of the initial consonant of nouns. Lenition changes the initial sound of the word (or name).

In addition, masculine nouns are slenderized if possible (that is, in writing, an 'i' is inserted before the final consonant) This also changes the pronunciation of the word.

Also, the particle a is placed before the noun unless it begins with a vowel (or f followed immediately by a vowel, which becomes silent when lenited). Examples of the use of the vocative personal names (as in Irish):

The name "Hamish" is just the English spelling of Sheumais (the vocative of Seumas and pronounced ), and thus is actually a Gaelic vocative. Likewise, the name "Vairi" is an English spelling of Mhàiri, the vocative for Màiri.

Manx

The basic pattern is similar to Irish and Scottish. The vocative is confined to personal names, in which it is common. Foreign names (not of Manx origin) are not used in the vocative. The vocative case causes lenition of the initial consonant of names. It can be used with the particle "y".

The name Voirrey is actually the Manx vocative of Moirrey (Mary).

Brythonic languages

Welsh

Welsh lacks case declension but marks vocative constructions by lenition of the initial consonant of the word, with no obligatory particle. Despite its use being less common, it is still used in formal address: the common phrase foneddigion a boneddigesau means "gentlemen and ladies", with the initial consonant of boneddigion undergoing a soft mutation; the same is true of gyfeillion ("[dear] friends") in which cyfeillion has been lenited. It is often used to draw attention to at public notices orally and written – teachers will say "Blant" (mutation of plant 'children') and signage such as one right show mutation of myfyrwyr 'students' to draw attention to the importance of the notice.

Germanic languages

English

The vocative is not a grammatical case in English. Expressions for which the vocative would be used in languages which have that case, are nominative in English. In translations of languages that use the vocative case, translators have sometimes added the particle "O" before the noun, as is often seen in the King James Version of the Bible: for example the Greek ὀλιγόπιστοι, vocative masculine plural (in Matthew 8:26), is translated "O ye of little faith". While it is not strictly archaic, it is sometimes used to "archaeise" speech; it is often seen as very formal, and sees use in rhetoric and poetry, or as a comedic device to subvert modern speech. Another example is the recurrent use of the phrase "O (my) Best Beloved" by Rudyard Kipling in his Just So Stories. O may be considered a form of clitic and should not be confused with the interjection oh. However, as the Oxford English Dictionary points out, "O" and "oh" were originally used interchangeably.

Modern English commonly uses the objective case for nouns of address but sets them off from the rest of the sentences with pauses as interjections, rendered in writing as commas (the vocative comma). Two common examples of nouns of address in English are the phrases "Mr. President" and "Madam Chairwoman".

Some traditional texts use Jesu, the Latin vocative form of Jesus. One of the best-known examples is Jesu, Joy of Man's Desiring.

German dialects

In some German dialects, like the Ripuarian dialect of Cologne, it is common to use the (gender-appropriate) article before a person's name. In the vocative phrase then the article is, as in Venetian and Catalan, omitted. Thus, the determiner precedes nouns in all cases except the vocative. Any noun not preceded by an article or other determiner is in the vocative case. It is most often used to address someone or some group of living beings, usually in conjunction with an imperative construct. It can also be used to address dead matter as if the matter could react or to tell something astonishing or just happening such as "Your nose is dripping."

Colognian examples:

Icelandic

The vocative case generally does not appear in Icelandic, but a few words retain an archaic vocative declension from Latin, such as the word Jesús, which is Jesú in the vocative. That comes from Latin, as the Latin for Jesus in the nominative is Jesus and its vocative is Jesu. That is also the case in traditional English (without the accent) (see above):

The native words sonur 'son' and vinur 'friend' also sometimes appear in the shortened forms son and vin in vocative phrases. Additionally, adjectives in vocative phrases are always weakly declined, but elsewhere with proper nouns, they would usually be declined strongly:

Norwegian

Nouns in Norwegian are not inflected for the vocative case, but adjectives qualifying those nouns are; adjectival adjuncts modifying vocative nouns are inflected for the definite (see: Norwegian language#Adjectives). The definite and plural inflections are in most cases identical, so it is more easily observable with adjectives that inflect for plural and definite differently, e.g. liten being lille when definite, but små when plural, an instance of suppletion.

In several Norwegian dialects, north of an isogloss running from Oslo to Bergen, names in argument position are associated with proprial articles, e.g. gendered pronouns such as han 'he' or hun 'she', which either precede or follow the noun in question. This is not the case when in vocative constructions.

Greek

In Ancient Greek, the vocative case is usually identical to the nominative case, with the exception of first-declension masculine nouns (ending in -ας or -ης), second-declension non-neuter nouns (ending in -ος) and third-declension non-neuter nouns.

In the first declension, masculines in -ᾱς have the vocative in -ᾱ (νεᾱνίᾱ); those in -της have -ᾰ (πολῖτα), all others in -ης have -η (Ἀτρείδη) except names of nations and compounds: Πέρσᾰ, Σκύθᾰ, γεω-μέτρᾰ, παιδο-τρίβᾰ. Δεσπότης has a recessive accent vocative δέσποτα. Second-declension masculine and feminine nouns have a regular vocative ending in -ε. Third-declension nouns with one syllable ending in -ς have a vocative that is identical to the nominative (νύξ, night); otherwise, the stem (with necessary alterations, such as dropping final consonants) serves as the vocative (nom. πόλις, voc. πόλι; nom. σῶμα, gen. σώματος, voc. σῶμα). Irregular vocatives exist as well, such as nom. Σωκράτης, voc. Σώκρατες.

In Modern Greek, second-declension masculine nouns still have a vocative ending in -ε. However, the accusative case is often used as a vocative in informal speech for a limited number of nouns, and always used for certain modern Greek person names: "Έλα εδώ, Χρήστο" "Come here, Christos" instead of "...Χρήστε". Other nominal declensions use the same form in the vocative as the accusative in formal or informal speech, with the exception of learned Katharevousa forms that are inherited from Ancient Greek Ἕλλην (Demotic Έλληνας, "Greek man"), which have the same nominative and vocative forms instead.

Iranian languages

Kurdish

Kurdish has a vocative case. For instance, in the dialect of Kurmanji, it is created by adding the suffix -o at the end of masculine words and the -ê suffix at the end of feminine ones. In the Jafi dialect of Sorani it is created by adding the suffix of -i at the end of names.

Instead of the vocative case, forms of address may be created by using the grammatical particles lê (feminine) and lo (masculine):

Indo-Aryan languages

Hindi-Urdu

In Hindi-Urdu (Hindustani), the vocative form is identical with the oblique, except that in the plural, ओं loses its nasalization. Adjectives in Hindi-Urdu also have a vocative case form. In the absence of a noun argument, some adjectives decline like masculine nouns that do not end in आ ā.

Sanskrit

In Sanskrit, the vocative (सम्बोधन विभक्ति sambodhana vibhakti) is morphologically distinct from the nominative only in the singular. In vowel-stem nouns, if there is a -ḥ in the nominative, it is omitted and the stem vowel may be altered: -ā and -ĭ become -e, -ŭ becomes -o, -ī and -ū become short and -ṛ becomes -ar. Consonant-stem nouns have no ending in the vocative:

Slavic languages

Old Church Slavonic

Old Church Slavonic has a distinct vocative case for many stems of singular masculine and feminine nouns, otherwise it is identical to the nominative. When different from the nominative, the vocative is simply formed from the nominative by appending either -e (rabŭ : rabe 'slave') or -o (ryba : rybo 'fish'), but occasionally -u (krai : kraju 'border', synŭ : synu 'son', vračĭ : vraču 'physician') and '-i' (kostĭ : kosti 'bone', gostĭ : gosti 'guest', dĭnĭ : dĭni 'day', kamy : kameni 'stone') appear. Nouns ending with -ĭcĭ have a vocative ending of -če (otĭcĭ : otĭče 'father', kupĭcĭ : kupĭče 'merchant'), likewise nouns ending with -dzĭ assume the vocative suffix -že (kŭnědzĭ : kŭněže 'prince'). This is similar to Greek, Latin, Lithuanian, and Sanskrit, which also employ the -e suffix in vocatives.

Bulgarian

Unlike most other Slavic languages, Bulgarian has lost case marking for nouns. However, Bulgarian preserves vocative forms. Traditional male names usually have a vocative ending.

More recent names and foreign names may have a vocative form but it is rarely used (Ричарде, instead of simply Ричард Richard, sounds unusual or humorous to native speakers).

Vocative phrases like господине министре (Mr. Minister) have been almost completely replaced by nominative forms, especially in official writing. Proper nouns usually also have vocative forms, but they are used less frequently. Here are some proper nouns that are frequently used in vocative:

Vocative case forms also normally exist for female given names:

Except for forms that end in -е, they can be considered rude and are often avoided, especially in some regions of Bulgaria. For female kinship terms, the vocative is always used:

Czech

In Czech, the vocative (vokativ, or 5. pád – 'the fifth case') usually differs from the nominative in masculine and feminine nouns in the singular.

It is a common dialectal feature of Czech to use the nominative with female names (Lojzka, dej pokoj!) or when following a title (pane učitel!, pane továrník!, pane Novák!). It is particularly prevalent in regional dialects, such as those of Moravia, where it has been the only form in use for hundreds of years.

The full vocative remains part of the official standard propagated by the Czech government. In the Czech Republic and elsewhere in eastern Europe, language competence is often conflated with adherence to official norms, and the use of the nominative - while common - may therefore be stigmatised.

Polish

In Polish, the vocative (wołacz) is formed with feminine nouns usually taking -o except those where the last consonant is soft e.g. -sia, -cia, -nia, and -dzia, which take -u. Feminine nouns that end with -i, usually in the suffixes -ini and -yni, as well as feminine nouns that end with a soft consonant, usually words with the suffix -(o)ść, but also irregular words like sól take the ending -i. Feminine nouns that end with a hardened consonant e.g. noc take the ending -y. Masculine nouns generally follow the complex pattern of the locative case, with the exception of a handful of words such as Bóg → Boże 'God', ojciec → ojcze 'father' and chłopiec → chłopcze 'boy'. Neuter nouns and all plural nouns have the same form in the nominative and the vocative:

The latter form of the vocative of człowiek 'human' is now considered poetical.

The nominative is increasingly used instead of the vocative to address people with their proper names. In other contexts the vocative remains prevalent. It is used:

• To address an individual with the function, title, other attribute, family role
  • Panie doktorze (Doctor!), Panie prezesie! (Chairman!)
  • Przybywasz za późno, pływaku (You arrive too late, swimmer)
  • synu (son), mamo (mum), tato (dad)
• After adjectives, demonstrative pronouns and possessive pronouns
  • Nie rozumiesz mnie, moja droga Basiu! (You don't understand me, my dear Basia!)
• To address an individual in an offensive or condescending manner:
  • Zamknij się, pajacu! ("Shut up, you buffoon!")
  • Co się gapisz, idioto? ("What are you staring at, idiot?")
  • Nie znasz się, baranie, to nie pisz! ("Stop writing, idiot, you don't know what you're doing!")
  • Spadaj, wieśniaku! ("Get lost, hillbilly!")
• After "Ty" (second person singular pronoun)
  • Ty kłamczuchu! (You liar!)
• Set expressions:
  • (O) Matko!, (O) Boże!, chłopie

The vocative is also often employed in affectionate and endearing contexts such as Kocham Cię, Krzysiu! ("I love you, Chris!") or Tęsknię za Tobą, moja Żono ("I miss you, my wife."). In addition, the vocative form sometimes takes the place of the nominative in informal conversations: Józiu przyszedł instead of Józio przyszedł ("Joey's arrived"). When referring to someone by their first name, the nominative commonly takes the place of the vocative as well: Ania, chodź tu! instead of Aniu, chodź tu! ("Anne, come here!").

Russian

Historic vocative

The historic Slavic vocative has been lost in Russian and is now used only in archaic expressions. Several of them, mostly of Old Church Slavonic origin, are common in colloquial Russian: "Боже!" (Bože, vocative of "Бог" Bog, "God") and "Боже мой!" (Bože moj, "My God!"), and "Господи!" (Gospodi, vocative of "Господь" Gospodj, "Lord"), which can also be expressed as "Господи Иисусе!" (Gospodi Iisuse!, Iisuse vocative of "Иисус" Iisus, "Jesus"). The vocative is also used in prayers: "Отче наш!" (Otče naš, "Our Father!"), or the Russian version of the Jesus Prayer ("Господи Иисусе Христе"). Such expressions are used to express strong emotions (much like English "O my God!"), and are often combined ("Господи, Боже мой"). More examples of the historic vocative can be found in other Biblical quotes that are sometimes used as proverbs: "Врачу, исцелися сам" (Vraču, iscelisia sam, "Physician, heal thyself", nom. "врач", vrač). Vocative forms are also used in modern Church Slavonic. The patriarch and bishops of the Russian Orthodox Church are addressed as "владыко" (vladyko, hegemon, nom. "владыка", vladyka). In the latter case, the vocative is often also incorrectly used for the nominative to refer to bishops and patriarchs. These Old Church Slavonic words that are present in the current Russian language are known as "fossil words".

New vocative

In modern colloquial Russian, given names and a small family of terms often take a special "shortened" form that some linguists consider to be a re-emerging vocative case. It is used only for given names and nouns that end in -a and -я, which are sometimes dropped in the vocative form: "Лен, где ты?" ("Lena, where are you?"). It is basically equivalent to "Лена, где ты?" but suggests a positive personal and emotional bond between the speaker and the person being addressed. Names that end in -я then acquire a soft sign: "Оль!" = "Оля!" ("Olga!"). In addition to given names, the form is often used with words like "мама" (mom) and "папа" (dad), which would be respectively shortened to "мам" and "пап". The plural form is used with words such as "ребят", "девчат" (nom: "ребята", "девчата" guys, gals).

Such usage differs from the historic vocative, which would be "Лено" and is not related.

Serbo-Croatian

In Serbo-Croatian languages, distinct vocatives exist only for singular masculine and feminine nouns. Nouns of the neuter gender and all nouns in plural have a vocative equal to the nominative. All vocative suffixes known from Old Church Slavonic also exist in Serbo-Croatian.

The vocative in Serbo-Croatian is formed according to one of three types of declension, which are classes of nouns with the same declension suffixes.

First declension

The first declension comprises masculine nouns that end with a consonant. These have a vocative suffix of either -e (doktor : doktore 'doctor') or -u (gospodar : gospodaru 'master').

Nouns terminating in -or have the -e vocative suffix: doktor : doktore 'doctor', major : majore 'major', majstor : majstore 'artisan', as well as nouns possessing an unsteady a: vetar : vetre 'wind', svekar : svekre 'father-in-law', and the noun car : care 'emperor'. All other nouns in this class form the vocative with -u: gospodar : gospodaru 'master', pastir : pastiru 'shepherd', inženjer : inženjeru 'engineer', pisar : pisaru 'scribe', sekretar : sekretaru 'secretary'.

In particular, masculine nouns ending with a palatal or prepalatal consonant j, lj, nj, č, dž, ć, đ or š form vocatives with the -u suffix: heroj : heroju 'hero', prijatelj : prijatelju 'friend', konj : konju 'horse', vozač : vozaču 'driver', mladić : mladiću 'youngster', kočijaš : kočijašu 'coachman', muž : mužu 'husband'.

Nouns ending with the velars -k, -g and -h are palatalized to -č, -ž, -š in the vocative: vojnik : vojniče 'soldier', drug : druže 'comrade', duh : duše 'ghost'. A final -c becomes -č in the vocative: stric : striče 'uncle', lovac : lovče 'hunter'. Likewise, a final -z becomes -ž in only two cases: knez : kneže 'prince' and vitez : viteže 'knight'.

The loss of the unsteady a can trigger a sound change by hardening consonants, as in vrabac : vrapče 'sparrow' (not *vrabče), lisac : lišče 'male fox' (not *lisče) and ženomrzac : ženomršče 'misogynist' (not *ženomrzče). There may be a loss of -t before -c like in otac : oče 'father' (instead of *otče), svetac : sveče 'saint' (instead of *svetče). When these phonetic alterations would substantially change the base noun, the vocative remains equal to the nominative, for example tetak 'uncle', mačak 'male cat', bratac 'cousin'. This also holds true for foreign names ending with -k, -g and -h like Džek 'Jack', Dag 'Doug', King, Hajnrih.

Male names ending with -o and -e have a vocative equal to the nominative, for example: Marko, Mihailo, Danilo, Đorđe, Pavle, Radoje.

Second declension

The second declension affects nouns with the ending -a. These are mainly of feminine but sometimes also of masculine gender. These nouns have a vocative suffix -o: riba : ribo 'fish', sluga : slugo 'servant', kolega : kolego 'colleague', poslovođa : poslovođo 'manager'.

Exemptions to this rule are male and female given names, which have a vocative equal to the nominative, e. g. Vera, Zorka, Olga, Marija, Gordana, Nataša, Nikola, Kosta, Ilija etc. However, this is different for twosyllabic names with an ascending accent such as female names Nâda, Zôra, Mîca, Nêna and male names Pêra, Bôža, Pâja, etc., which form vocatives with -o: Nâdo, Zôro, Mîco, Pêro, Bôžo, Pâjo, etc.

Denominations of relatives like mama 'mom', tata 'dad', baba 'grandmother', deda 'grandfather', tetka 'aunt' (parent's sister), ujna 'aunt' (mother's brother's wife), strina 'aunt' (father's brother's wife) have vocatives equal to the nominative. This also holds true for country names ending in -ska, -čka, -ška.

Nouns ending with the diminutive suffix -ica that consist of three or more syllables have a vocative with -e: učiteljica: učiteljice "female teacher", drugarica: drugarice "girlfriend", tatica: tatice "daddy", mamica: mamice "mommy". This also applies to female names Danica: Danice, Milica: Milice, Zorica: Zorice, and the male names Perica: Perice, Tomica: Tomice. Nouns of this class that can be applied to both males and females usually have a vocative ending of -ico (pijanica: pijanico "drunkard", izdajica: izdajico "traitor", kukavica: kukavico "coward"), but vocatives with -ice are also seen.

The use of vocative endings for names varies among Serbo-Croatian dialects. People in Croatia often use only nominative forms as vocatives, while others are more likely to use grammatical vocatives.

Third declension

The third declension affects feminine nouns ending with a consonant. The vocative is formed by appending the suffix -i to the nominative (reč : reči 'word', noć : noći 'night').

Slovak

Until the end of the 1980s, the existence of a distinct vocative case in Slovak was recognised and taught at schools. Today, the case is no longer considered to exist except for a few archaic examples of the original vocative remaining in religious, literary or ironic contexts:

In everyday use, the Czech vocative is sometimes retrofitted to certain words:

Another stamp of vernacular vocative is emerging, presumably under the influence of Hungarian for certain family members or proper names:

Ukrainian

Ukrainian has retained the vocative case mostly as it was in Proto-Slavic:

There are some exceptions:

It is used even for loanwords and foreign names:

It is obligatory for all native names:

It is used for patronymics:

Latin

In Latin, the form of the vocative case of a noun is almost always the same as the nominative. Exceptions include singular non-neuter second-declension nouns that end in -us in the nominative case. An example would be the famous line from Shakespeare, "Et tu, Brute?" (commonly translated as "And you, Brutus?"): Brute is the vocative case and Brutus would be the nominative.

Nouns that end in -ius end with -ī instead of the expected -ie. Thus, Julius becomes Julī and filius becomes filī. The shortening does not shift the accent so the vocative of Vergilius is Vergilī, with accent on the second syllable even though it is short. Nouns that end in -aius and -eius have vocatives that end in -aī or -eī even though the -i- in the nominative is consonantal.

First-declension and second-declension adjectives also have distinct vocative forms in the masculine singular if the nominative ends in -us, with the ending -e. Adjectives that end in -ius have vocatives in -ie so the vocative of eximius is eximie.

Nouns and adjectives that end in -eus do not follow the rules above. Meus forms the vocative irregularly as mī or meus, while Christian Deus does not have a distinct vocative and retains the form Deus. "My God!" in Latin is thus mī Deus!, but Jerome's Vulgate consistently used Deus meus as a vocative. Classical Latin did not use a vocative of deus either, preferring to use the name of the god (and in reference to pagan gods, the Romans used the suppletive form dive).

Greek names in Latin texts conserve their Greek vocative form. E. g., the vocative of Andrēās is Andrēā.

Romance languages

West Iberian languages

Portuguese drops the article to form the vocative. The vocative is always between commas and, like in many other languages, a particle Ó is commonly used:

In Extremaduran and Fala, some post-tonical vowels open in vocative forms of nouns, a new development that is unrelated to the Latin vocative case.

Catalan

Catalan drops the article to form the vocative.

French

Like English, French sometimes uses (or historically used) a particle Ô to mark vocative phrases rather than by change to the form of the noun. A famous example is the title and first line of the Canadian national anthem, O Canada (French title: Ô Canada), a vocative phrase addressing Canada.

Romanian

The vocative case in Romanian is partly inherited, occasionally causing other morphophonemic changes (see also the article on Romanian nouns):

• singular masculine/neuter: -e as in
  • om: omule! (man, human being),
  • băiat: băiete! or băiatule! (boy),
  • văr: vere! (cousin),
  • Ion: Ioane! (John);
• singular feminine: -o as in
  • soră: soro! (sister),
  • nebună: nebuno! (mad woman), also in masculine (nebunul)
  • deșteaptă: deșteapto! (smart one (f), often used sarcastically),
  • Ileana: Ileano! (Helen);

Since there is no -o vocative in Latin, it must have been borrowed from Slavic: compare the corresponding Bulgarian forms сестро (sestro), откачалко (otkachalko), Елено (Eleno).

• plural, all genders: -lor as in
  • frați: fraților! (brothers),
  • boi: boilor! (oxen, used toward people as an invective),
  • doamne și domni: doamnelor și domnilor! (ladies and gentlemen).

In formal speech, the vocative often simply copies the nominative/accusative form even when it does have its own form. That is because the vocative is often perceived as very direct and so can seem rude.

Romanesco dialect

In Romanesco dialect the vocative case appears as a regular truncation immediately after the stress.

Compare (vocative, always truncated)

France', vie' qua!

"Francesco/Francesca, come here!"

with (nominative, never truncated)

Francesco/Francesca viene qua

"Francesco/Francesca comes here"

Venetian

Venetian has lost all case endings, like most other Romance languages. However, with feminine proper names the role of the vocative is played by the absence of the determiner: the personal article ła / l' usually precedes feminine names in other situations, even in predicates. Masculine names and other nouns lack articles and so rely on prosody to mark forms of address:

Predicative constructions:
