In the English language, in broad terms, there are past, present and future tenses, which have some relevance to time. i.e. Past Simple, Present Simple and Future Simple (except, of course the present simple tense, which doesn't really refer to time at all but is used in a more indefinite sense. e.g. I like coffee.)The verb structure changes to reflect the time factor. e.g. I jumped. I jump. I will jump.In addition to time, tenses can also indicate the continuance and/or completeness of an action etc.e.g. I was jumping (past continous), I am jumping (present continuous), I will be jumping (future continuous), I have jumped (present perfect), I have been jumping (present perfect continuous).This means that we also have such tenses as the continuous tense, the perfect tense, the imperfect tense, the perfect continuous tense, etc etc, and we can see from the examples above that the Present Simple tense clearly differs from the Present Continuous tense.So there are also tenses such as the Present Perfect Simple, Present Perfect Continuous, and Past Perfect Simple, Past Perfect Continuous, Future Perfect Continuous.Furthermore there is the passive form (or passive voice), which is/are sometimes termed to as the passive tense(s) e.g. The Past Passive Tense (per Oxford University Press).

I finished my research paper two days early.
the simple tenses of verbsThe simple present and the simple past are termed "simple" because they are expressed by direct inflection on the verb. English verbs are not inflected for future tense, but expressions with the modal will are often spoken of as "future tense." Some grammars use the term tense to refer what are technically tense and aspect combinations: present perfect, past perfect, present progressive, past progressive, present perfect progressive, and past perfect progressive. Very occasionally, voice (i.e. passive) is treated as a kind of tense.Finally, some authorities use emphatic tense to refer to some or all constructions using the modal do. Only the basic present and past forms qualify as simple.(Present, Past, and Future)
Singular and plural are verb forms found only in the active voice of the present tense, at least in English. Verb forms and tenses have to do with what kind of action and when it happened. English has a lot of verb forms: Present Past Future I go I went I will go I do go I did go I am going I was going I have gone I had gone I will have gone That is just the beginning!
