Forming the past tense of regular verbs is simple, right? We just add the letters “ed” to the end of the base form of the verb. However, how we say the “ed ” ending on the verb changes. There are actually three different sounds that we use to say the same “ed” ending! Here are three simple rules to help:
#1 When the base form (infinitive) of the verb ends in the letter “t” or “d”, we say the “ed” ending like “id” and this adds another syllable to the verb.
#2 When the base form (infinitive) of the verb ends in a consonant that is not voiced (p, k, f, x, ss, sh, ch), we say the “ed” ending like “t”.
#3 When the base form (infinitive) of the verb ends in a consonant that is voiced (all other ending sounds), we say the “ed” ending like “d”.
