Grammar Unit 5: Lesson 2
Regular/Irregular Verbs

2. Regular Verbs
A regular verb forms its past and past participle by adding –ed or –d to the base form.
Some regular verbs undergo spelling changes when –ed is added
Ex. spy + -ed = spied
trot + -ed = trotted
refer + -ed = referred

3. Irregular Verbs
An irregular verb forms its past and past participle in some way other than by adding -ed or –d to the base form.
Ex. be  was, were  been
bear  bore  borne
leave  left  left
choose  chose  chosen
And many more… (An irregular verbs reference sheet will be uploaded to the website with this lesson.)
