These are principally questions of terminology, not grammatical fact, and have no practical importance. In Practical English Usage the term 'tense' is used for all verb forms and structures that indicate time. 2tenses and timeThere is not a direct relationship between verb forms and time. For example, a past verb like went is not only used to talk about past events (e.g. We went to Morocco last January), but also about unreal or uncertain present or future events (e.g. It would be better if we went home now). And present verbs can be used to talk about the future (e.g. I'm seeing Daniel tomorrow). Also, progressive and perfect forms express ideas that are not simply concerned with time – for example continuation, completion, present importance.3table of active verb tensesThis is a list of all the active affirmative forms of an ordinary English verb, with their names, examples, and very brief descriptions of typical uses. For more information about the forms and their uses, see the entries for each tense in Section 3, Section 4, Section 5.
