Understanding subject-verb agreement is essential in English grammar. When writing or speaking, it’s crucial to ensure that the subject and verb in a sentence agree in number and person. This article aims to explore the rules of subject-verb agreement and provide examples to help clarify any confusion.
What is Subject-Verb Agreement
Subject-verb agreement is the correspondence of a verb with its subject in number (singular or plural) and person (first, second, or third). In English, a verb must agree with its subject in person and in number. This means that a singular subject takes a singular verb, while a plural subject takes a plural verb.
Rules of Subject-Verb Agreement
Understanding the rules of subject-verb agreement is essential for constructing grammatically correct sentences. Here are some important rules to keep in mind:
- Rule 1: A singular subject takes a singular verb, and a plural subject takes a plural verb.
- Rule 2: When the subject of a sentence is compound (consisting of two or more nouns or pronouns connected by “and”), use a plural verb.
- Rule 3: When the subject is a collective noun, use a singular verb if the group is considered as a single unit. Use a plural verb if the members of the group are acting as individuals.
- Rule 4: When the subject is indefinite, such as “each,” “every,” “either,” “neither,” or “one,” use a singular verb.
- Rule 5: Some words that end in “-s” are singular and require a singular verb. These words include “mathematics,” “physics,” “news,” and “measles.”
Examples of Subject-Verb Agreement
Examining examples is an effective way to illustrate subject-verb agreement in practice. Below are examples that demonstrate proper subject-verb agreement based on the rules mentioned:
- Rule 1: The cat chases the mouse. (singular subject and singular verb)
- Rule 1: The cats chase the mice. (plural subject and plural verb)
- Rule 2: Sam and John are going to the beach. (compound subject and plural verb)
- Rule 3: The team is playing well. (collective noun as a single unit and singular verb)
- Rule 3: The team are warming up before the game. (members of the group acting individually and plural verb)
- Rule 4: Each student has a textbook. (indefinite subject and singular verb)
- Rule 5: Mathematics is my favorite subject. (word ending in “-s” treated as singular with a singular verb)
Common Errors in Subject-Verb Agreement
Mistakes in subject-verb agreement are prevalent, leading to grammatically incorrect sentences. Identifying and understanding common errors can help avoid making these mistakes. Some common errors include:
- Errors with compound subjects: Incorrect: The cat and the dog is playing. Correct: The cat and the dog are playing.
- Errors with collective nouns: Incorrect: The family is celebrating their anniversary. Correct: The family is celebrating its anniversary.
- Errors with indefinite subjects: Incorrect: Everyone are welcome to join. Correct: Everyone is welcome to join.
Identifying these common errors and learning how to correct them is crucial in achieving proper subject-verb agreement in sentences.
Subject-Verb Agreement in Different Tenses
Subject-verb agreement also applies to different tenses in English. Whether a sentence is in the present, past, or future tense, the subject and verb must still agree. Here are examples of subject-verb agreement in different tenses:
- Present tense: The bird sings in the morning. (singular subject and singular verb)
- Past tense: The birds sang in the morning. (plural subject and plural verb)
- Future tense: The team will be practicing tomorrow. (subject-verb agreement in the future tense)
Subject-Verb Agreement in Questions
When forming questions, it’s essential to ensure that the subject and verb still agree. Inverted word order in questions might lead to confusion, but the same rules of subject-verb agreement still apply. Here are examples of subject-verb agreement in questions:
- Is the cat chasing the mouse? (singular subject and singular verb)
- Are the cats chasing the mice? (plural subject and plural verb)
