Regular and irregular verbs:

Regular and irregular verbs:

Verbs have different forms. The three common verb forms are present tense, past tense, and past participle.

Most verbs are called regular verbs. Their past and participle forms are formed by adding -d or -ed to the present tense. The past participle requires the auxiliary verb have, has, or had. Here are some examples:

 

Present	Past	Past Participle
walk	walked	(have, has, had) walked
jump	jumped	(have, has, had) jumped
hike	hiked	(have, has, had) hiked
sip	sipped	(have, has, had) sipped
cry	cried	(have, has, had) cried

 

Some verbs are called irregular verbs. The past tense and past participle of irregular verbs do not end in -d or -ed. They can change the spelling or not at all. Here are some examples:

 

Present	Past	Past Participle
begin	began	(have, has, had) begun
see	saw	(have, has, had) seen
come	came	(have, has, had) come
give	gave	(have, has, had) given
hit	hit	(have, has, had) hit
know	knew	(have, has, had) known
teach	taught	(have, has, had) taught
