This document provides examples and rules for using the present indefinite tense in English. The present indefinite tense is used to express habitual or daily actions in the present time. It explains that the first form or base form of the verb is used in positive sentences. Auxiliary verbs like "do" or "does" are used in negative and interrogative sentences, along with the base verb form without adding "s" or "es". Several examples are given for positive, negative and interrogative sentences to illustrate the rules for using the present indefinite tense.

Present Indefinite Tense
It is used to express an action in present time, habitual or usual actions or daily event or
universal fact. It is used to express an action in present time which is usually done on a
regular basis. For example a student says, “I go to school”. It is a daily activity of a
student to go to school, so such actions are expressed by present simple tense.
Another example is, “I work in a factory”. It tells about a usual action of a person that he
works in a factory on regular basis.
