Irregular Verbs
What are they?
The way a verb forms its past
tense determines its
classification as regular or
irregular. A regular verb takes
the –d or –ed ending to denote
the past tense.
Irregular verbs do not take
the –d or –ed ending. They are
inflected in various other
ways to indicate past tense.
Examples
Regular
believe → believed
smile → smiled
Irregular
run → ran
eat → ate
An irregular verb forms its past
and past participle by
 changing vowels (run- ran) or
consonants (build– built)
 or by changing vowels and
consonants (catch – caught)
 or by making no changes (burst,
cost)
