What are the 4 main parts of verb?

It seems like you're asking about the parts of a verb, but the term "4 main parts" is a bit misleading when it comes to verbs. The typical breakdown focuses on verb tenses, not "parts." Here's a clearer explanation:

Verb Tenses

The four main verb tenses are:

1. Present Tense: Describes actions happening now. Example: "I walk."

2. Past Tense: Describes actions that happened in the past. Example: "I walked."

3. Future Tense: Describes actions that will happen in the future. Example: "I will walk."

4. Present Perfect Tense: Describes actions that started in the past and continue to the present or have a result in the present. Example: "I have walked."

Additional Points

* These tenses are often further divided into "simple" and "continuous" forms, as well as "perfect" forms like the Present Perfect.

* Verbs also have different moods (indicative, imperative, subjunctive) and voices (active and passive).
