The term 'Forms of Verbs' refers to the various ways in which verbs can be conjugated. This includes the different tenses, such as past, present, and future, as well as other forms such as the imperative, subjunctive, and passive. Tenses are a way of expressing the time frame in which an action takes place, and they are used to indicate when something happened or will happen. By changing the form of the verb, the meaning of the sentence can be changed. For example, the sentence 'I am eating' is in the present tense, while 'I ate' is in the past tense.
