Middle English (in the general sense 'time'): from Old French tens, from Latin tempus 'time'
Strictly speaking, in the terminology of modern grammar, English only has two tenses: past and present:
|verb||present tense||past tense|
|past||I walked||I was walking||I had walked||I had been walking|
|present||I walk||I am walking||I have walked||I have been walking|
|future||I shall/will walk||I shall/will be walking||I shall/will have walked||I shall/will have been walking|
