Grammar Rules for Verb Forms

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.
