Regular and irregular verbs

regular verb is any verb whose conjugation follows the typical pattern, or one of the typical patterns, of the language to which it belongs.  verb whose conjugation follow a different pattern are called irregular verbs.

In English, for example, verbs such as playenter, and like are regular since they form their inflected parts by adding the typical endings -s-ing and -ed to give forms such as playsentering, and liked. On the other hand, verbs such as drinkhit and have are irregular since some of their parts are not made according to the typical pattern: drank and drunk (not "drinked"); hit (as past tense and past participle, not "hitted") and has and had (not "haves" and "haved").

In the context of verbs, we use the term inflection to talk about the process of changing a verb form to show tense, mood, number (i.e. singular or plural), and person (i.e. first person, second person, or third person). This section deals with inflecting verbs to show tenses and participles, and is divided into two main sections:

Regular verbs

Irregular verbs

Regular verbs

Many English verbs are regular, which means that they form their different tenses according to an established pattern. Such verbs work like this:

Verb 3rd person singular
present tense
3rd person singular
past tense
past participle present participle
laugh he/she laughs he/she laughed laughed laughing
love he/she loves he/she loved loved loving
boo he/she boos he/she booed booed booing

Present tense formation

In the present simple tense, the basic form of a regular verb only changes in the 3rd person singular, as follows:

Most verbs just add -to the basic form (e.g. take/takesseem/seems, look/looks).

Verbs that end with a vowel other than e add -es (e.g. go/goes, veto/vetoes, do/does).

Verbs that end with -s, -z-ch, -sh, and -x add -es (e.g. kiss/kissesfizz/fizzespunch/puncheswash/washesmix/mixes).

If the verb ends in a consonant plus -y, change the y to an i before adding -es (e.g. hurry/hurriesclarify/clarifies). But if the verb ends in a vowel plus -y, just add -s (e.g. play/playsenjoy/enjoys).

Past tense formation

Forming the past simple tense of regular verbs is mostly straightforward, and you use the same form for the first, second, and third persons, singular and plural:

If the basic form of the verb ends in a consonant or a vowel other than e, add the letters -ed to the end (e.g. seem/seemedlaugh/laughedlook/looked).

For verbs that end in -e, add -d (e.g. love/lovedrecede/recededhope/hoped).

If the verb ends in a consonant plus -y, change the y to an before adding -ed (e.g. hurry/hurriedclarify/clarified). But if the verb ends in a vowel plus -y, just add -ed (e.g. play/playedenjoy/enjoyed).

Forming participles

To form the past participle of regular verbs, follow the same rules as for the past simple tense above.

To make the present participle of regular verbs:

If the basic form of the verb ends in a consonant or a vowel other than e, add the ending -ing (e.g. laugh/laughing, boo/booing).

If the verb ends in e, drop the e before adding -ing (e.g. love/loving, hope/hoping).

If the basic form ends in y just add -ing (e.g. hurry/hurrying, clarify/clarifying).
