Conjugation of verbs

The conjugation of the English verb is based on the 4 main forms. The first 2 forms are finite, the other 2 are non-finite.

The first is the present tense form which is equivalent to the infinitive without to and is used to form The Pre­sent Indefinite (Simple) Tense: come, read, clean, work, cry, etc. For example: I work every day. My children never cry.

The exception is the verb to be which has three pre­sent tense forms: am — in the first person singular, is — in the third person singular, and are — in the plural: I am a teacher. He is a pilot. We are friends. They are late. You are my only friend.

In the third person singular the present tense form takes the -(e)s suffix: He works every day. My daughter never cries. The exceptions are the verbs have and do. Their forms in the third person singular are has and does. He has nothing to do. She does all the homework. The second is the past tense form, came, read, cleaned, worked, cried, etc. Be has two forms: was, were.

As the above examples show there is a formal dif­ference between the past tense forms. This is due to the type of a particular verb.
