Tense Definition

Tense is used to show the relation between the action or state described by the verb and the time, which is reflected in the form of the verb. There are two basic tenses in English; the present tense and the past tense. The present is like the base form, although the third person singular adds -s. Regular verbs add -ed or -d to show the past tense, while irregular verbs change in many different ways, or not at all in some cases.
