Grammar

Regular and Irregular Verbs

Read the following sentence carefully.

On her own, she cleaned the hut and yard, tended the chickens, washed her clothes in the
river, carried water, cut firewood and cooked her solitary meals.

The verbs in the above sentence are in the simple past tense.

Most verbs form their past tense forms by adding -d or -ed to their base forms. They are
called regular verbs. If the base form of the verb has only one vowel sound and ends in a
consonant, we double the consonant and add -ed. If the base form ends with the letter y,
we replace the y with -ied. Read the following list of regular verbs and their simple past
forms.
