Grammatical tense 时态
(重定向自Tenses)
In grammar, tense is a category that expresses time reference. Tenses are usually manifested by the use of specific forms of verbs, particularly in their conjugation patterns.
Basic tenses found in many languages include the past, present and future. Some languages have only two distinct tenses, such as past and non-past, or future and non-future. There are also tenseless languages, like Chinese, which do not have tense at all. On the other hand, some languages make finer tense distinctions, such as remote vs. recent past, or near vs. remote future.
