Simple Present Tense Explanation and Formula

Simple present tense is formed from verb-1 (present tense) in the form of a regular verb denoting an action or state, or in the form of a verb "to be" (is, am, are).

Verb-1 is a bare infinitive with the addition of -s or -es (except verb to be) specifically for subjects in the form of a singular noun (such as: Tita, book) or third person singular pronoun (such as: she, he, it); or without any additions to the subject in the form of plural nouns (such as: boys, men, books) or plural pronouns (such as: we, they), pronouns I/you, or compound subjects with the hyphen "and" (such as: you and I, Tina and Ratih).
