Phla–Pherá languages

Capo's initial classification

Much of the comparative research for Hounkpati B.C. Capo's influential classification of the Gbe languages was carried out in the seventies, and partial results trickled down in the late seventies and early eighties in the form of articles on specific phonological developments in various branches of Gbe. In his 1988 work Renaissance du Gbe, the internal classification of Gbe was published in full for the first time (part of the introduction in his 1991 A Comparative Phonology of Gbe is an English translation of this). In this classification, Phla–Pherá is considered one of the five branches of Gbe, the others being Ewe, Gen, Fon, and Ajá. According to Capo (1988:15), the Phla–Pherá group consists of the following lects:

• Alada (Allada, Arda) – southwest Nigeria, southeast of Porto-Novo.
• Tɔli (Tori) – Atlantique and Weme Province, west of the Alada area.
• Tɔfin (Toffi, Tofin) – Weme province, Benin, north of Nokoué Lake.
• Phelá (Fida, Péda, Xwela, Phera) – east of Lake Ahémé in the Atlantique province of Benin.
• Phla (Pla, Xwla, Hwla, Popo) – in the coastal borderland of Togo and Benin, between Anexo and Grand Popo.
• Ayizɔ (Ayizo, Ayize) – Atlantique province, Benin.
• Kotafon (Kotafohn) – Mono Province, Benin.
• Gbési (Gbesi) – Mono province, north of Ahéme Lake, Benin.
• Tsáphɛ (Sahwe, Saxwe) – northern Mono province, Benin.
• Sɛ (Se) – west Mono province, Benin.

Ayizɔ, Gbesi (gbesiin) and Kotafɔn (kógbè) are the same basic language.

Capo grouped the Phla–Pherá lects mainly on the basis of a number of shared phonological and morphological features, including the development of proto-Gbe and into and , the retained distinction between and , and the occurrence of various nominal prefixes.

Capo noted that ‘the name Phla–Pherá is not used by speakers of the various lects which it comprises’ and that ‘in fact, the Phla–Pherá section is less unified than the others’. However, according to Capo, their speakers ‘recognise a closer link between the lects listed here than between any of those listed in other [branches]’. He marked the Alada variety as an exception, as some people 'consider Alada and the Fon language Gun to be one and the same language'.

Subsequent research

In the early nineties, the Summer Institute of Linguistics initiated a study to assess which Gbe communities could benefit from existing literacy efforts and whether additional development programs in some of the remaining communities would be needed. Linguistic research carried out in the course of this study was to shed more light on the relations between the various varieties of Gbe. Some of the results of this study were presented in Kluge (2000, 2005, 2006).

Based on a synchronic analysis of lexical and grammatical features elicited among 49 Gbe varieties, Kluge divided the Gbe languages into three major groupings: western, central, and eastern. The eastern grouping consists of three clusters: Fon (roughly equivalent to Capo's 'Fon' branch), western Phla–Phera, and eastern Phla–Phera (together roughly equivalent to Capo's Phla–Pherá languages). Among other things, this part of Kluge's analysis confirmed the uncertainty of the classification of the Alada dialect: some possible results point to inclusion in the Fon group, while others suggest membership of one of the Phla–Pherá clusters. Likewise, Kluge's results indicate uncertainty regarding the classification of Ayizo and Kotafon.

A number of lects considered by Kluge were not included in Capo's research (cf. Capo 1991:14ff), namely Ajra, Daxe, Gbesi, Gbokpa, Movolo, Se, and Seto, all of which Kluge (2000:32, 2005:41ff,47, 2006:74ff,79) classified as Phla–Phera.

Linguistic diversity

Just like Capo readily admitted the considerable diversity of the Phla–Pherá branch, Kluge's analysis did not result in conclusive evidence regarding the exact make-up of the western and eastern Phla–Pherá branches – various modes of computation yielded different configurations of the respective dialects (cf. 2000:62–3, 2005:45ff). The diversity in this subfamily is probably due in part to the fact that the various Phla–Pherá communities do not occupy one specific geographical area but are scattered along the coast of the Bight of Benin.

However, a more substantial reason for the noted diversity is one of historical nature. In a 1979 work on the history of the Gbe peoples (called Adjatado back then), the Catholic missionary Roberto Pazzi pointed out that 'three dialects emerged from the half-breeding between immigrant groups and the indigenes from Tádó: they are Gɛ̀n, Sáhwè and Xweɖá.' The latter two dialects are part of Capo's Phla–Pherá branch, and Capo adds that Tsáphɛ and Phelá have Cábɛ (Yoruboid) and E̟do respectively as substrata. This contact and intermingling of non-Gbe peoples with Gbe peoples and the influence of this processes on language inevitably diffuses the picture presented by comparative linguistic research. Further research into the historical origins of the Phla and Pherá peoples has yet to take place.

Due to the uncertainty about the internal structure of the eastern Gbe major grouping, the Ethnologue has omitted Phla–Pherá altogether from its subclassification of Gbe languages. Some of the lects of Capo's and Kluge's Phla–Pherá are included in other branches (for example, Xwla is found under Aja) while others are not included in any subgroup of Gbe (e.g. Xwela).
