In reference to verbs in the English language, the word tense means "time." The tenses of verbs indicate the time and the state in which a verb is.There are the present, past, and future tenses.
As opposed to other languages such as the Romance languages with twelve to fourteen different tenses, which, along with Latin and Anglo-Saxon are part of the ancestry of the language, English has only six tenses: Present, Past, Future, Present Perfect, Past Perfect, and Future Perfect. But, each tense has three forms: Basic, Progressive, and Emphatic. Here is an example of the tenses for one verb, using the subject "He" and the regular verb "hear":
Present - He hears
Past - He heard
Future - He will hear
Present Perfect - He has heard
Past Perfect - He had heard
Future Perfect - He will have heard.
Re: The Perfect tenses: The word "Perfect" is derived from the Latin, meaning completed. So, the Present Perfect is an action completed in the present; the Past Perfect, an action completed in the past, and the Future Perfect, an action completed in the future.
Present Progressive - He is hearing
Past Progressive - He was hearing
Future Progressive - He will be hearing
Present Perfect Progressive - He has been hearing
Past Perfect Progressive - He had been hearing
Future Perfect Progressive - He will have been hearing
Present Emphatic - He does hear
Past Emphatic - He did hear
