Subject-Verb Agreement refers to the rule that the subject and verb in a sentence must agree in number. This means:

Basic Rules of Subject-Verb Agreement

1. Singular subjects take singular verbs:
   Example: The dog barks.

3. When the subject is separated from the verb by a phrase or clause, the verb agrees with the main subject:
   Example: The boy, along with his friends, is playing.
4. Subjects joined by "and" usually take a plural verb:
   Example: John and Mary are coming.
5. Subjects joined by "or" or "nor" agree with the subject closest to the verb:
   Example: Either the teacher or the students are responsible.
6. Indefinite pronouns (e.g., everyone, nobody) take singular verbs:
   Example: Everyone is excited.
7. Uncountable nouns take singular verbs:
   Example: Water flows freely.

Examples of Subject-Verb Agreement

• The cat runs quickly. (Singular subject: cat, Singular verb: runs)
• The children play in the park. (Plural subject: children, Plural verb: play)
• Each of the books is on the shelf. (Indefinite pronoun: each, Singular verb: is)
