We have learned that regular verbs of the weak conjugation form their past tense and perfect participle by adding ed or d to the present tense form.

Point out how the following verbs form their past tense and perfect participle:

Present.Past.Perfect Participle.
mean,meant, meant.
sleep,slept, slept.
say,said, said.
cost,cost, cost.

In some verbs the ed or d of the past tense is sounded like t, and in many cases the spelling has changed to t. A few verbs shorten the vowel of the present; as, feel, felt, felt. Other verbs of this conjugation change the vowel before adding d; as, tell, told, told; and a number that end in t or d make no change; as, set, set, set.
