What Is Sub Verb Agreement

Subject-Verb Agreement: A Comprehensive Guide

Subject-verb agreement, a cornerstone of grammatical accuracy, refers to the correspondence between the subject of a sentence and its verb in number and person. In simpler terms, it means the verb must agree with its subject in whether it's singular or plural. Mastering subject-verb agreement is crucial for clear and effective communication, both in written and spoken English. This comprehensive guide will delve into the intricacies of subject-verb agreement, exploring various scenarios and providing clear examples to solidify your understanding.

Understanding the Basics

Before diving into complex scenarios, let's establish the fundamental principle: singular subjects take singular verbs, and plural subjects take plural verbs.

• Singular: The dog barks loudly. (Singular subject, singular verb)
• Plural: The dogs bark loudly. (Plural subject, plural verb)

The key lies in correctly identifying the subject of the sentence. The subject is the noun or pronoun performing the action described by the verb. Sometimes, identifying the subject can be tricky, especially in complex sentences. We will address these challenges later in this guide.

Common Challenges and Exceptions

While the basic rule seems straightforward, numerous exceptions and complexities can complicate subject-verb agreement. Let's address some common challenges:

1. Intervening Phrases

Phrases placed between the subject and the verb do not affect the verb's agreement with the subject. These phrases often begin with words like with, along with, as well as, in addition to, besides, except, and including.

• Incorrect: The cat, along with its kittens, play in the yard.
• Correct: The cat, along with its kittens, plays in the yard. (The subject is "cat," which is singular.)

2. Compound Subjects Joined by "And"

Compound subjects joined by "and" generally take a plural verb.

• The dog and the cat chase each other.

However, there's an exception: if the compound subject refers to a single entity or concept, a singular verb is used.

• Peanut butter and jelly is my favorite sandwich. (Peanut butter and jelly is considered a single food item.)

3. Compound Subjects Joined by "Or," "Nor," "Either...or," "Neither...nor"

When compound subjects are joined by or, nor, either...or, or neither...nor, the verb agrees with the subject closest to it.

• Neither the dogs nor the cat wants to go outside.
• Either the cat or the dogs are making that noise.

4. Collective Nouns

Collective nouns (e.g., team, family, group, committee) can be singular or plural depending on the context. If the group acts as a single unit, use a singular verb. If the members of the group are acting individually, use a plural verb.

• The team is playing well this year. (The team acts as a unit.)
• The team are arguing amongst themselves. (The members of the team are acting individually.)

The same principle applies to other collective nouns like family, class, crowd, and audience.

5. Indefinite Pronouns

Indefinite pronouns like everyone, someone, anyone, no one, everybody, somebody, anybody, nobody, each, and one are always singular and take singular verbs.

• Everyone is invited to the party.
• Somebody has left their book on the table.

However, indefinite pronouns such as both, few, many, several are always plural and take plural verbs.

• Many are called, but few are chosen.

6. Subjects That Appear Plural But Are Singular

Some nouns that appear plural in form (ending in -s) are actually singular and take singular verbs. Examples include:

• Measles is a contagious disease.
• News is spreading quickly.
• Physics is my favorite subject.

7. Inverted Sentence Structure

In sentences with inverted structures (where the verb comes before the subject), be careful to identify the subject correctly to ensure proper agreement. This is common in questions and sentences beginning with there or here.

• There are many reasons for this decision. (Subject: reasons)
• Here is the book you requested. (Subject: book)

8. Parenthetical Phrases

Parenthetical phrases (phrases set off by commas that add extra information) do not affect subject-verb agreement.

• The students, along with their teacher, are going on a field trip. (The subject is "students.")

9. Units of Measurement

Units of measurement generally take singular verbs.

• Ten pounds is a good weight for this package.

10. Titles of Works

Titles of books, movies, and other works are always singular, even if they appear plural in form.

• "The Grapes of Wrath" is a classic novel.

Advanced Considerations

The complexities of subject-verb agreement become even more apparent when dealing with more intricate sentence structures. Let's examine some scenarios that require careful consideration.

1. Relative Clauses

Relative clauses (clauses introduced by relative pronouns like who, whom, whose, that, and which) can sometimes complicate subject-verb agreement. The verb in the relative clause agrees with the antecedent (the noun or pronoun the relative pronoun refers to).

• The dog, which is barking loudly, is disturbing the neighbors. (The verb "is barking" agrees with "dog.")

2. Compound Sentences

Compound sentences (sentences with two or more independent clauses) require careful attention to subject-verb agreement in each clause.

• The birds are singing, and the flowers are blooming. (Each clause has correct subject-verb agreement.)

3. Fractional Expressions

Fractional expressions can be tricky. The verb agrees with the noun following the fraction or percentage.

• One-third of the students are failing the class. (The noun "students" is plural)
• One-third of the pizza is left. (The noun "pizza" is singular)

4. "None" as a Subject

The pronoun none can take either a singular or plural verb depending on the context. If it refers to a singular countable noun, use a singular verb; otherwise use a plural verb.

• None of the cake is left.
• None of the students are passing the exam.

5. Gerunds and Infinitives as Subjects

Gerunds (verbs ending in -ing used as nouns) and infinitives (to + verb) are always treated as singular subjects.

• Running is good exercise.
• To err is human.

Strategies for Mastering Subject-Verb Agreement

To master subject-verb agreement, you need consistent practice and a keen eye for detail. Here are some useful strategies:

• Identify the subject: Always start by identifying the main subject of your sentence. Ignore intervening phrases.
• Determine the number: Is the subject singular or plural?
• Choose the correct verb: Select the verb that agrees in number with the subject.
• Read your sentences aloud: Reading your writing aloud can help you catch errors in subject-verb agreement that you might miss when reading silently.
• Practice regularly: The key to mastering subject-verb agreement is consistent practice. Work through exercises and review the rules periodically.
