Subject-Verb Agreement refers to the grammatical rule that the subject of a sentence must agree with the verb in both number (singular or plural) and person. Here’s an overview of the key rules for subject-verb agreement:

 1. Singular Subjects Take Singular Verbs

– If the subject is singular, the verb must also be singular.
– Example:- The cat runs quickly.
– She is very talented.

 2. Plural Subjects Take Plural Verbs

– If the subject is plural, the verb must be plural as well.
– Example:
– The cats run quickly.
– They are very talented.

 3. Compound Subjects

– If two subjects are connected by “and,” they typically take a plural verb.
– Example:
– John and Mary are going to the store.

– However, if the subjects form a single entity or idea, they take a singular verb.
– Example:
– Peanut butter and jelly is my favorite snack.

 4. Subjects Joined by “Or” or “Nor”

– When subjects are joined by “or” or “nor,” the verb agrees with the part of the subject closest to it.
– Example:
– Either the teacher or the students are responsible for organizing the event.
– Neither the students nor the teacher is coming to the party.

5. Indefinite Pronouns

– Singular indefinite pronouns (e.g., everyone, someone, each, either) take singular verbs.
– Example:
– Everyone wants to succeed.
– Each of the students has a book.

– Plural indefinite pronouns (e.g., several, few, many) take plural verbs.
– Example:
– Several people are attending the meeting.
– Few know the truth.

– Some indefinite pronouns (e.g., all, some) can be singular or plural depending on the context.
– Example:
– All of the cake is gone.
– All of the cupcakes are eaten.

 6. Collective Nouns

– Collective nouns (e.g., team, family, group) can take either singular or plural verbs depending on whether the group is acting as a single unit or as individuals.
– Example:
– The team is winning the game. (acting as a single unit)
– The team are arguing amongst themselves. (acting as individuals)

 7. Inverted Sentence Structures

– When the subject comes after the verb (in sentences beginning with “here” or “there”), the verb must agree with the actual subject, not “here” or “there.”
– Example:
– There is a book on the table.
– Here are the keys you were looking for.

 8. Titles and Proper Nouns

– Titles of books, movies, and other works take a singular verb even if they are plural in form.
– Example:
– “The Chronicles of Narnia” is a popular fantasy series.

 9. Plural Form, Singular Meaning

– Some nouns that are plural in form but singular in meaning take singular verbs (e.g., news, mathematics, physics).
– Example:
– Mathematics is challenging.

 10. Amounts of Time, Money, Distance

– Amounts of time, money, distance, etc., when considered as a single unit, take a singular verb.
– Example:
– Five dollars is enough to buy that.
– Ten miles is a long way to walk.

 11. Gerunds and Infinitives as Subjects

– When a gerund or an infinitive acts as the subject, it takes a singular verb.
– Example:
– Swimming is fun.
– To run fast requires practice.
