Regular verbs in English have four forms:
Wiktionary entries display these forms in the headword line, for example:
Many irregular verbs distinguish the past tense (simple past or preterite) from the past participle. See Appendix:English irregular verbs for more information about irregular verbs.
English regular verbs follow one of the five rules listed in this table:
Rule | Special inflection | Example verb | Modern forms | Archaic forms |
---|---|---|---|---|
The base form ends with silent e | The -e is omitted when the suffix begins with a vowel | love | loves, loving, loved | lovest, loveth |
The base form ends with -y not preceded by a vowel | The -y becomes -ie- when the suffix begins with a consonant or -e- | cry | cries, crying, cried | criest, crieth |
The base form ends with a sibilant without silent e | An -e- is inserted if the suffix begins with a sibilant | latch | latches, latching, latched | latchest, latcheth |
The base form ends with a single vowel followed by a single consonant | The consonant is often doubled when the suffix begins with a vowel (depending on a complex set of rules) |
strut | struts, strutting, strutted | struttest, strutteth |
fathom | fathoms, fathoming, fathomed | fathomest, fathometh | ||
travel | British: travels, travelling, travelled | travellest, travelleth | ||
American: travels, traveling, traveled | travelest, traveleth | |||
The base form is not covered by these criteria | none | listen | listens, listening, listened | listenest, listeneth |
Example: walk
English forms the perfect tenses with a verb phrase made up of the auxiliary verb have plus the past participle of the main verb (e.g., love).
Verb | Present perfect | Past perfect | Future perfect |
---|---|---|---|
love | has/have loved | had loved | will/shall have loved |
go | has/have gone | had gone | will/shall have gone |
In addition to the regular perfect tenses, English can create other variations with various other auxiliary verbs. The verb phrase in the main clause of the first example could be called a conditional perfect tense:

The auxiliary verb have plus a following past participle indicates the perfect aspect.
The auxiliary verb be plus a following present participle indicates the continuous aspect
Modal verbs (such as can, must, would, etc.) occur only once per verb in most varieties of English. Each has a different meaning and they go before have and be, in that order.
