There are also tenseless languages, like most of the Chinese languages, though they can possess a future and nonfuture system typical of Sino-Tibetan languages. Some languages have only two distinct tenses, such as past and nonpast, or future and nonfuture. The main tenses found in many languages include the past, present, and future. Tenses are usually manifested by the use of specific forms of verbs, particularly in their conjugation patterns.
In grammar, tense is a category that expresses time reference.
