THE REGULAR VERBS
• Forming Regular Simple Past Tense Verbs
• To form the simple past of most regular verbs in English, simply add the suffix -ed to
the base form of the verb. The base form of a verb is defined as the infinitive without
the preposition to infinitive marker. For example:
Infinitive – Base – Simple Past
• to accept – accept – accepted
• to count – count – counted
• to follow – follow – followed
• to listen – listen – listened
• to wash – wash – washed
Some English verbs require some spelling changes between the base form and the simple past.
For verbs that are spelled with a “silent” e on the end of the word, remove the “silent” e and
then add the -ed suffix. For example:
Infinitive – Base – Simple Past
• to care – care – cared
• to decide – decide – decided
• to introduce – introduce – introduced
• to realize – realize – realized
• to use – use – used

For verbs that are spelled with a y on the end of the word, change the y to an i and then add
the -ed suffix. For example:
Infinitive – Base – Simple Past
• to copy – copy – copied
• to deny – deny – denied
• to party – party – partied
• to study – study – studied
• to worry – worry – worried
