Simple present


The simple present, present simple or present indefinite is one of the verb forms associated with the present tense in modern English. It is commonly referred to as a tense, although it also encodes certain information about aspect in addition to present time. The simple present is the most commonly used verb form in English, accounting for more than half of verbs in spoken English.
It is called "simple" because its basic form consists of a single word, in contrast with other present tense forms such as the present progressive and present perfect. For nearly all English verbs the simple present is identical to the base form of the verb, except when the subject is third-person singular, in which case the ending -s is added. There are a few verbs with irregular forms, the most notable being the copula be, which has the simple present forms am, is, and are.

Conjugation

For pronouns I, you, we, they, there is no modification for verbs.
For pronouns he, she, it, a suffix is added following these rules:
For verbs that end in -o, -ch, -sh, -s, -x, or -z, the suffix -es is added
Examples:
For verbs that end in a consonant + y, the letter y is replaced by the suffix -ies.
Examples:
In other cases, the suffix -s is added.
Examples:
And a special situation happens with the verb "to have" in which the letters ve are omitted before adding s.
Example:
The basic form of the simple present is the same as the base form of the verb, unless the subject is third person singular, in which case a form with the addition of -s is used. For details of how to make this inflected form, see.
The copula verb be has irregular forms: am, is and are. The modal verbs have only a single form, with no addition of -s for the third person singular.
The above refers to the indicative mood of the simple present; for the formation and use of the subjunctive mood, see English subjunctive.

Negative

The present simple of lexical verbs has an expanded form which uses do as an auxiliary verb. This is used particularly when forming questions and other clauses requiring inversion, negated clauses with not, and clauses requiring emphasis. For details see do-support. For the verbs which do not make this form, as well as the formation and use of contracted forms such as 's, isn't, and don't, see English auxiliaries and contractions.
