Subject/Verb Agreement

Subject-Verb Agreement Rules

1. Basic Rule:

   • A singular subject takes a singular verb, while a plural subject takes a plural verb.
   • Example:
     • Singular: The cat runs fast.
     • Plural: The cats run fast.

2. 
   

3. Adding -s or -es:

   • In the present simple tense, we typically add -s or -es to the base form of the verb when the subject is singular.

4. 
   

5. When to Use -s:

   • Add -s to most verbs when the subject is a singular noun or pronoun (he, she, it).
   • Example:
     • She plays soccer.
     • He reads a book.

6. 
   

7. When to Use -es:

   • Add -es to verbs that end in:
     • -s, -sh, -ch, -x, or -z.
   • Example:
     • He watches TV.
     • She finishes her homework.

8. 
   

9. Irregular Verbs:

   • Some verbs are irregular and do not follow the standard rules. For example, the verb "to be" has different forms:
     • I am happy.
     • You are happy.
     • He/She/It is happy.

10. 
    

11. Plural Subjects:

    • For plural subjects (they, we, you, or plural nouns), do not add -s or -es to the verb.
    • Example:
      • They play soccer.
      • We read books.

Common Pitfalls

• Collective Nouns: Collective nouns (e.g., team, group) can be tricky. They may take a singular or plural verb depending on whether the group acts as a single unit or as individuals.

  • Example:
    • The team wins the game. (acting as one unit)
    • The team are arguing among themselves. (acting as individuals)
    • 
      

• Compound Subjects: When two subjects are joined by "and," they are usually plural.

  • Example:
    • Tom and Jerry are friends.

Understanding Collective Nouns

1. Collective Nouns as Singular:

   • When the collective noun refers to the group as a single unit, it takes a singular verb.
   • Example: The team is winning the game.
     • In this case, "the team" is viewed as one entity or unit that is engaged in a single action (winning).

2. 
   

3. Collective Nouns as Plural:

   • When the focus is on the individual members of the group acting separately or having different opinions, the collective noun takes a plural verb.
   • Example: The family are discussing their plans.
     • Here, "the family" is viewed as individual members who are each contributing to the discussion, thus acting separately.

     
     

   • Remember:

   • • • The choice between singular and plural verbs depends on the context of the sentence.
     • • In American English, collective nouns are often treated as singular, while in British English, they can be treated as plural.
