English is a West Germanic language, which was first used by Britain in the Middle Ages and became the most widely used language in the world because of its vast colonies.
tenses:
*** is divided into 16 kinds.
In grammar, tense or tense indicates the relationship between the time when an action occurs and the time when it is spoken. Generally, it can be divided into past tense, present tense and future tense, and it is usually used together with progressive tense and perfect tense which indicate the progress or termination of action.
Tense, together with mood, voice, aspect and the form of people called verbs, can show at least five grammatical features.
In some languages, tenses are not used, such as Chinese in analytic language, but when necessary, they are still assisted by adverbs of time. In some languages, such as Japanese, the morphological changes of adjectives can express temporal information and have temporal properties similar to verbs. In some languages, such as Russian, one word can express tense and aspect.
