Grammar Rules for Verb Forms

The verb form depends on the subject and the context of the sentence.
The correct verb form is determined by the subject-verb agreement.

Verb Forms for Different Subjects

For singular subjects (e.g., the new employee, the play), the verb form is usually in the third person singular (e.g., is interviewing, is being directed).
For plural subjects (e.g., the women, the geese), the verb form is usually in the plural form (e.g., are going, are flying).
For irregular plural nouns (e.g., tooth, foot, mouse), the verb form is usually in the plural form (e.g., are hurting, are running, are pulling).

Verb Forms for Different Tenses

For present tense, the verb form is usually in the present simple (e.g., play, fly, swim, cry, drive).
For past tense, the verb form is usually in the past simple (e.g., went, saw, had, traveled).
For future tense, the verb form is usually in the future simple (e.g., will go, will see, will have).

Conditional Sentences

If-clauses use the past perfect (e.g., had snowed, had enough money) or the past simple (e.g., had, would have gone).
Main clauses use the conditional perfect (e.g., would have gone, would have traveled) or the conditional simple (e.g., would travel, would buy).

Tag Questions

Tag questions use the auxiliary verb (e.g., do, does, did) and the subject-verb agreement.
Examples: doesn't it?, is it?, didn't she?, are they?

Comparisons

Comparisons use the comparative form (e.g., stronger, more expensive) or the superlative form (e.g., the strongest, the most expensive).
Examples: He is stronger than his brother, This phone is more expensive than the one I bought last year.
