Appendix:English verbs

For detailed information about English verbs, see English verbs on WikipediaWikipedia . This appendix entry provides a simple summary.

Regular verbs in English have four forms:

The base form, for example, listen.
The third-person singular (he/she/it) present form, for example, listens.
The present participle (gerund), for example, listening.
The past form, for example, listened.

Wiktionary entries display these forms in the headword line, for example:

listen (third-person singular simple present listens, present participle listening, simple past and past participle listened)

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.

Conjugation of regular verbs in English

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

Tense and aspect

Perfect tenses

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:

"He would have ridden his bicycle if it had not rained."
"She was about to have gone home." (Or "She was going to have gone home.")
"They had been going for a swim every Thursday."

The auxiliary verb have plus a following past participle indicates the perfect aspect.

I have walked a lot today.

The auxiliary verb be plus a following present participle indicates the continuous aspect

I am walking right now

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.

He must have been [past participle] walking [present participle] for ages.
