hi

how many tenses are there in english language

[Casiopea]

That depends on how tense is defined. Everyone has an opinion on the matter, and there doesn't seem to be a consensus yet. (See one poll here).

You wouldn't be wrong, though, if you said that there are only two tenses in English, past and non-past.

As for the kinds of verbs there are, there's a verb list here: Verb Tense Chart
