Subject-Verb Agreement
The subject and verb in a sentence must agree in number (singular or plural).
beginnerVerb-FormsDifficulty: 1/10
Explanation
Basic Rules:
- Singular subjects take singular verbs (add -s or -es)
- Plural subjects take plural verbs (no -s or -es)
- Third person singular always adds -s or -es to the verb
Special Cases:
- Collective nouns can be singular or plural depending on context
- Indefinite pronouns (everyone, somebody) are usually singular
- Subjects joined by 'and' are usually plural
Examples
[{"correct": "The cat runs fast.", "incorrect": "The cat run fast.", "explanation": "Singular subject 'cat' needs singular verb 'runs'"}, {"correct": "The cats run fast.", "incorrect": "The cats runs fast.", "explanation": "Plural subject 'cats' needs plural verb 'run'"}, {"correct": "She walks to school.", "incorrect": "She walk to school.", "explanation": "Third person singular 'she' requires verb + s"}, {"correct": "Everyone is here.", "incorrect": "Everyone are here.", "explanation": "Indefinite pronoun 'everyone' is singular"}]
