Verb Tenses

Perfect verbs show actions that are finished, like “I have eaten”. To use the perfect tense, we need the past participle of a verb.

Irregular verbs don’t follow the usual rules for changing tense. Irregular verbs are unique and often require memorizing like “go” is “went”.

Modal verbs are special verbs that add meaning to the main verb in a sentence. They show possibility, ability, permission, or obligation. 

The past perfect tense talks about actions completed before another past moment. It helps understand the sequence of past events.

We use the future perfect tense when there is an action that will be finished by a certain time – “By 2030, we will have landed on Mars.”

The present perfect tense form combines “have” or “has” with the past participle of a verb. It shows actions that are finished in the present.
