The simple present or present simple 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.It is called "simple" because its basic form consists of a single word (like write or writes), in contrast with other present tense forms such as the present progressive (is writing) and present perfect (has written). For nearly all English verbs the simple present is identical to the base form (dictionary form) of the verb, except when the subject is third-person singular, in which case the ending -(e)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.The principal use of the simple present is to refer to an action or event that takes place habitually, as in He writes for a living (in contrast to the present continuous, which refers to something taking place at the present moment: He is writing a letter now). However certain verbs expressing a state, such as be and know, are used in the simple present even when referring to a temporary present state. There are also certain other uses (including those mentioned in the following paragraph) in which the simple present does not reflect a habitual aspect.Like other English present tense forms, the simple present has certain uses in which it does not refer to present time. It frequently refers to the future, as in "My train leaves tomorrow" and "If we win on Saturday, ...". It can also sometimes refer to past events – as in newspaper headlines, for example.For more information about the uses of constructions related to or contrasting with the simple present, see Uses of English verb forms.
