Subject-verb agreement is very important because without it, the reader can be confused Subjects and verbs must agree in number.
We have 12 basic rules when it comes to subject verb agreement.
If the subject is singular, the verb must be singular too.Example: She writes every dayIf the subject is plural, the verb must also be plural.Example: They write every day.When the subject of the sentence is composed of two or more nouns or pronouns connected by and, use a plural verb.Example: The doctoral student and the committee members write every day.When there is one subject and more than one verb, the verbs throughout the sentence must agree with the subject.Example: Interviews are one way to collect data and allow researchers to gain an in-depth understanding of participants.
The subject is usually a noun—a word (or phrase) that names a person, place, or thing. The verb (or predicate) usually follows the subject and identifies an action or a state of being.
The words and phrases "each," "eachone," "either," "neither," "everyone,""everybody," "anyone," "anybody,""nobody," "somebody," "someone," and "noone" are singular and require a singular verb.Example: Each of the participants was willingto be recorded.Noncountnouns take a singular verb.Example: Education is the key to success.
When a phrase comes between the subject and the verb, remember that the verb still agrees with the subject, not the noun or pronouncing the phrase following the subject of the sentence.Example: The student, as well as the committee members, is excited.When two or more singular nouns or pronouns are connected by "or" or "nor," use a singular verb.Example: The chairperson or the CEO approves the proposal before proceeding.When a compound subject contains both a singular and plural noun or pronoun joined by "or" or "nor," the verb should agree with the part of the subject that is closest to the verb. This is also called the rule of proximity.Example: The student or the committee members write everyday.
Some countable nouns in English such as earnings, goods, odds, surroundings, proceeds, contents, and valuables only have a plural form and take a plural verb.Example: The earnings for this quarter exceed expectations.In sentences beginning with "there is" or "there are," the subject follows the verb. Since "there" isn't the subject, the verb agrees with what follows the verb.Example: There is little administrative support.
