REGULAR AND IRREGULAR VERBS

This post discussed the properties of regular and irregular verbs as well as their usage

Regular Verb
Those verbs that form their past participle with ‘d’ or ‘ed’ are regular verbs. These verbs do not undergo substantial changes while changing forms between tenses.

If the verb ends with a vowel, only ‘d’ is added. For example:

PRESENT TENSE	PAST TENSE
SHARE	SHARED
SCARE	SCARED
DARE	DARED

If the verb ends with a consonant, ‘ed’ is added. For example:

PRESENT TENSE	PAST TENSE
WANT	WANTED
SHOUT	SHOUTED
KILL	KILLED

Irregular Verbs

Those verbs that undergo substantial changes when changing forms between tenses are irregular verbs. The changed forms of these verbs are often unrecognizable different from the originals. For example:

PRESENT TENSE	PAST TENSE
Go	Went
Run	Ran
Think	Thought
