Through Uses of English verb forms, Syntax and English modal auxiliary verbs

The term simple is used to distinguish the syntactical construction whose basic form uses the plain past tense alone, from other past tense constructions which use auxiliaries in combination with participles, such as the present perfect, past perfect, and past progressive.

Formation

Regular verbs form the past simple end-ed; however there are a few hundred irregular verbs with different forms. The spelling rules for forming the past simple of regular verbs are as follows: verbs ending in -e add only –d to the end (e.g. live – lived, not *liveed), verbs ending in -y change to -ied (e.g. study – studied) and verbs ending in a group of a consonant + a vowel + a consonant double the final consonant (e.g. stop – stopped). For details see English verbs § Past tense.

Most verbs have a single form of the past simple, independent of the person or number of the subject (there is no addition of -s for the third person singular as in the present simple). However, the copula verb be has two past tense forms: was for the first and third persons singular, and were in other instances. The form were can also be used in place of was in conditional clauses and the like; for information on this, see English subjunctive. This is the only case in modern English where a distinction in form is made between inversion, negations with not, and emphatic forms of the past simple use the auxiliary did. For details of this mechanism, see do-support. A full list of forms is given below, using the (regular) verb help as an example:

  • Basic past simple:
    • I/you/he/she/it/we/they helped
  • Expanded (emphatic) past simple:
    • I/you/he/she/it/we/they did help
  • Question form:
    • Did I/you/he/she/it/we/they help?
  • Negative:
    • I/you/he/she/it/we/they did not (didn't) help
  • Negative question:
    • Did I/you/he/she/it/we/they not help? / Didn't I/you/he/she/it/we/they help?
