Rules of Subject-Verb Agreement: Most English learners are well aware of the structure like you are, we are, he is, etc. But they often fail to connect the subject and its verb in a little longer sentence that changes the meaning of a sentence. To avoid this failure, we must identify the actual subject and the main verb in a sentence. This article will teach you the rules of subject-verb agreement and provide examples so that you can see how they are applied.
Rules of Subject-Verb Agreement
Rule-1: The subject of a sentence must agree with its verb in number, i.e., they both must be in the correct form (both are singular or both plural).
Examples
- That boy eats mangoes.
- Those boys eat mangoes.
- He shares his books with his friends.
- My brother always drives to work.
- They enjoy music.
It does not matter how many qualifiers divide the subject and verb. They must always be linked.
Further Examples
- A bag with two cell phones was found in the class.
- The number of questions he asked me is increasing my knowledge.
In the first sentence, the subject is “A bag,” not the cell phones. So, the verb that goes with it is singular.
In the second sentence, the is refers to the number, not to questions; therefore, we put the verb in the singular form because the is singular.
It will be beneficial to remember that is, was, has. Most verbs ending in a single “s”are singular, for example, plays, works, thinks, studies, etc. the other verbs like have, are, were, and verbs not ending in a single “s” is plural; for example, they study, we go, you play, etc.
Rule-2: When two singular nouns or pronouns are the subject of a sentence and are joined by and the verb must be plural.
Examples
- Ahmad and Saleem are best friends.
- Physics and biology are lengthy subjects.
- Were your brother and sister at home last night?
- Oil and water do not mix.
- The walls and the furniture of this school were beautifully decorated.
But the two or more nouns or pronouns connected by and proposed the idea of a singular person or thing to the mind, or it is referred to the same person or thing previously stated the verb must be singular.
Examples
- Our professor and adviser is in the office.
- Bread and butter is eaten by him.
- My class fellow and engineer was dead.
- Bread and butter is a popular food.
Rule-3: Subordinate clauses don’t affect subject-verb agreement when they are placed between the subject and verb.
Example
- The book you brought last night was written by my favorite author.
- The man who went to the school was not returned.
Rule-4: When we place a prepositional phrase between the subject and verb does not affect the subject-verb agreement.
Example
- The design of the house is beautiful.
- The performance of the two young players was very impressive.
Rule-5: A unit of time or measurement always takes a singular verb.
Example
- Thirty minutes is reserved for each test.
Rule-6: Two infinitives joined by “and” require the verb in plural form.
Example
- To listen and to read required significant attention.
Rule-7: If the words each, every, or no precede the subject in a sentence, the verb must always be singular.
Example
- Every student and teacher is needed to be present.

Rule-8: Some sentences begin with “there” or “here,” the subjects of such sentences will always remain after the verb.
Examples

- Here are the books you requested.
Rule-9: When the subject is singular and some other words connected to that singular subject by “with, as well as, along with, together with, like, unlike, nothing but, besides, accompanied by, including, and in addition to” the verb must be put in the singular form.
