Subject-Verb Agreement - Detailed explanation
Subject-verb agreement is one of the most fundamental grammar rules in English and a critical component of verbal ability tests in Philippine civil service examinations. This rule states that a subject and its verb must agree in number (singular or plural) and person (first, second, or third). Mastering subject-verb agreement is essential for success in the CSE, UPCAT, LET, and other professional examinations. Understanding these rules will help you identify correct sentences, spot grammatical errors, and communicate more effectively in both written and spoken English.
Concepts
Basic Subject-Verb Agreement Rules
The fundamental principle of subject-verb agreement is that singular subjects take singular verbs (with -s ending in present tense), while plural subjects take plural verbs (base form). The verb must match the subject in both number and person. In present tense, singular subjects in third person (he, she, it) require verbs ending in -s or -es, while plural subjects and first/second person subjects take the base form of the verb.
Examples
'Student' is singular, so it takes the singular verb 'studies' (study + s). This follows the basic rule that singular subjects require singular verbs.
Scenario
Simple present tense with singular subject
Solution
The student studies hard every day.
'Students' is plural, so it takes the plural verb 'study' (base form). Plural subjects always take the base form of the verb.
Scenario
Simple present tense with plural subject
Solution
The students study hard every day.
'She' (singular) takes 'is', while 'They' (plural) takes 'are'. The verb 'to be' has unique forms for different subjects.
Scenario
Using 'to be' verb forms
Solution
She is a nurse. They are doctors.
Applications
- Identifying correct verb forms in multiple-choice questions
- Writing grammatically correct sentences in essays
- Proofreading and editing written documents
- Speaking with proper grammar in professional settings
Misconceptions
- Thinking that nearby plural nouns affect the verb when the actual subject is singular
- Confusing collective nouns as always plural when they can be singular
- Using plural verbs with indefinite pronouns that are actually singular
Related Concepts
- Indefinite pronouns
- Collective nouns
- Compound subjects
- Inverted sentences
Common Exam Questions
Example
The teacher (teach/teaches) mathematics. Answer: teaches (singular subject needs singular verb)
Approach
Look for subject-verb disagreement by identifying the subject first, then checking if the verb matches in number
Question Type
Error identification
Example
Each of the students _____ their homework. Answer: does (Each is singular despite the plural noun following)
Approach
Identify the subject, determine if it's singular or plural, then choose the appropriate verb form
Question Type
Sentence completion
Key Points To Remember
- Singular subjects take singular verbs (verb + s/es)
- Plural subjects take plural verbs (base form)
- Third person singular requires -s form: he runs, she sings
- First and second person take base form: I run, you sing
- The verb 'to be' has special forms: am, is, are, was, were
Tricky Subject-Verb Agreement Situations
Many sentences contain elements that can confuse the identification of the true subject, leading to agreement errors. These include prepositional phrases, subordinate clauses, and inverted sentence structures. The key is to identify the simple subject by removing modifying phrases and clauses that come between the subject and verb.
Examples
'Box' is the subject, not 'pencils'. The prepositional phrase 'of pencils' modifies 'box' but doesn't change the fact that 'box' is singular, so it takes 'is'.
Scenario
Prepositional phrase between subject and verb
Solution
The box of pencils is on the table.
'There' is an expletive, not the subject. The real subject is 'students' (plural), so the verb is 'are'. Rearranged: Many students are in the classroom.
Scenario
Expletive construction
Solution
There are many students in the classroom.
In questions, identify the subject by converting to statement form. 'Book' is singular, so it takes 'is'.
Scenario
Interrogative sentence
Solution
Where is your book? (Your book is where?)
Applications
- Analyzing complex sentence structures in reading comprehension
- Writing clear and grammatically correct complex sentences
- Identifying subjects in formal documents and contracts
- Editing and proofreading professional communications
Misconceptions
- Thinking the noun closest to the verb is always the subject
- Believing 'there' and 'here' are subjects in expletive constructions
- Getting confused by the word order in questions
Related Concepts
- Prepositional phrases
- Expletive constructions
- Inverted sentences
- Interrogative sentences
Common Exam Questions
Example
The group of singers (are/is) performing tonight. Answer: is (group is singular, ignore 'of singers')
Approach
Cross out prepositional phrases and modifying clauses to find the true subject
Question Type
Identify the error
Example
There (is/are) several reasons for the delay. Answer: are (several reasons are there)
Approach
Rearrange inverted sentences to normal order to identify subject clearly
Question Type
Sentence correction
Key Points To Remember
- Ignore prepositional phrases when determining subject-verb agreement
- Cross out modifying clauses to find the true subject
- In inverted sentences, find the subject that comes after the verb
- Expletives 'there' and 'here' are not subjects
- In questions, rearrange to statement form to identify subject
Indefinite Pronouns and Agreement
Indefinite pronouns refer to non-specific people or things and have specific agreement rules. Some are always singular, some are always plural, and others can be either singular or plural depending on context. Understanding these categories is crucial for correct subject-verb agreement.
Examples
'Everyone' is always singular despite referring to multiple people. It takes the singular verb 'is'.
Scenario
Always singular indefinite pronoun
Solution
Everyone is invited to the party.
'Some' takes singular verb when referring to uncountable noun (cake), but plural verb when referring to countable plural noun (students).
Scenario
Context-dependent indefinite pronoun
Solution
Some of the cake is gone. Some of the students are absent.
'A number of' (meaning several/many) is plural, while 'The number of' (specific quantity) is singular.
Scenario
Number expressions
Solution
A number of books are missing. The number of books is increasing.
Applications
- Writing formal reports and academic papers
- Understanding statistical and research language
- Completing standardized test questions
- Professional communication and presentations
Misconceptions
- Thinking 'everyone' and 'everybody' are plural because they refer to many people
- Confusing 'a number of' with 'the number of'
- Not considering the context for pronouns like 'some', 'all', 'most'
Related Concepts
- Collective nouns
- Quantifiers
- Countable and uncountable nouns
- Pronoun reference
Common Exam Questions
Example
Each of the participants (have/has) received a certificate. Answer: has (each is always singular)
Approach
Categorize the indefinite pronoun as always singular, always plural, or context-dependent
Question Type
Pronoun-verb agreement
Example
Most of the information (is/are) accurate. Answer: is (information is uncountable, so singular)
Approach
For context-dependent pronouns, look at the noun in the 'of' phrase to determine singular or plural
Question Type
Contextual agreement
Key Points To Remember
- Always singular: each, every, either, neither, one, someone, anyone, everyone, nobody, somebody, anybody, everybody
- Always plural: both, few, many, several
- Singular or plural based on context: all, any, most, none, some (depend on the noun they refer to)
- Words ending in -one, -body, -thing are singular
- 'A number of' is plural; 'The number of' is singular
Compound Subjects and Special Cases
Compound subjects involve two or more subjects connected by conjunctions. The agreement rules vary depending on the conjunction used and whether the subjects are considered as one unit or separate entities. Special cases include subjects connected by correlative conjunctions and subjects that appear plural but are grammatically singular.
Examples
Two subjects joined by 'and' create a plural compound subject, so the verb 'are' is plural.
Scenario
Compound subject with 'and'
Solution
John and Mary are coming to the party.
'Bread and butter' represents one food item, so it takes the singular verb 'is'.
Scenario
Compound subject as one unit
Solution
Bread and butter is my favorite snack.
With 'either...or', the verb agrees with the nearest subject. 'Students' is plural, so 'are' is used.
Scenario
Either...or construction
Solution
Either the teacher or the students are responsible.
'Along with her students' is a modifying phrase, not part of the subject. The subject is 'teacher' (singular), so 'is' is used.
Scenario
Subject with modifying phrase
Solution
The teacher, along with her students, is attending the seminar.
Applications
- Writing complex sentences with multiple subjects
- Understanding legal and business documents
- Academic writing and research papers
- Formal presentations and reports
Misconceptions
- Thinking all subjects connected by conjunctions are plural
- Not recognizing when compound subjects represent one unit
- Treating modifying phrases as part of compound subjects
Related Concepts
- Coordinating conjunctions
- Correlative conjunctions
- Modifying phrases
- Collective nouns
Common Exam Questions
Example
The manager and his assistant (is/are) in a meeting. Answer: are (true compound subject)
Approach
Determine if subjects are truly compound (joined by 'and') or if one is just a modifying phrase
Question Type
Compound subject identification
Example
Neither the books nor the pen (is/are) mine. Answer: is (pen is singular and nearest to verb)
Approach
With either...or, neither...nor, make the verb agree with the subject closest to the verb
Question Type
Correlative conjunction agreement
Key Points To Remember
- Subjects joined by 'and' are usually plural
- Exception: compound subjects representing one unit take singular verbs
- With 'or', 'nor', 'either...or', 'neither...nor' - verb agrees with nearest subject
- Phrases like 'as well as', 'together with', 'along with' don't create compound subjects
- Some nouns are plural in form but singular in meaning (news, mathematics, physics)
Collective Nouns and Quantity Expressions
Collective nouns refer to groups of people or things as a single unit but can be tricky for subject-verb agreement. They can be singular when the group acts as one unit, or plural when emphasizing individual members. Quantity expressions, measurements, and time periods also have special agreement rules.
Examples
'Team' is acting as one unit, so it takes the singular verb 'is'.
Scenario
Collective noun as one unit
Solution
The team is practicing for the championship.
Here, individual team members are acting separately, so the plural verb 'are' is used.
Scenario
Collective noun emphasizing individuals
Solution
The team are arguing among themselves about the strategy.
The amount of money is considered as one unit, so it takes the singular verb 'is'.
Scenario
Money expression
Solution
Five thousand pesos is enough for the project.
The fraction agrees with the noun it modifies: 'students' (plural) takes 'are', 'water' (singular) takes 'is'.
Scenario
Fraction agreement
Solution
Two-thirds of the students are present. Two-thirds of the water is clean.
Applications
- Business and organizational communication
- Statistical reports and data presentation
- Academic research and scientific writing
- News reporting and journalism
Misconceptions
- Always treating collective nouns as plural
- Not considering context when determining collective noun agreement
- Thinking all expressions with numbers are plural
Related Concepts
- Group nouns
- Quantifiers
- Measurement expressions
- Fractional expressions
Common Exam Questions
Example
The jury (has/have) reached its decision. Answer: has (acting as one unit)
Approach
Determine if the collective noun is acting as one unit (singular) or emphasizing individuals (plural)
Question Type
Collective noun agreement
Example
Twenty kilometers (is/are) a long distance. Answer: is (distance measurement is singular)
Approach
For measurements, money, and time, use singular verbs; for fractions, look at the noun being modified
Question Type
Quantity expression agreement
Key Points To Remember
- Collective nouns are usually singular when acting as one unit
- Use plural verbs when emphasizing individual actions within the group
- Money, time, distance, and measurement expressions are usually singular
- Fractions and percentages agree with the noun they modify
- Titles and proper nouns ending in -s are usually singular
Practice Problems
The subject is 'committee' (singular collective noun acting as one unit), not 'experts' which is part of a prepositional phrase. Collective nouns typically take singular verbs when acting as one unit.
Problem
The committee of experts (is/are) reviewing the proposal.
Solution
is
With 'neither...nor', the verb agrees with the subject nearest to the verb. 'Teacher' is singular and closest to the verb, so 'was' (singular) is correct.
Problem
Neither the students nor the teacher (was/were) prepared for the surprise quiz.
Solution
was
'Everyone' is an indefinite pronoun that is always singular, regardless of the modifying phrase 'in the three classes'. Singular subjects take singular verbs.
Problem
Everyone in the three classes (has/have) submitted their assignments.
Solution
has
In expletive constructions with 'there', the verb agrees with the real subject that follows. 'Reasons' is plural, so 'are' is correct. Rearranged: Several reasons are there.
Problem
There (is/are) several reasons why the project was delayed.
Solution
are
'News' is a noun that is plural in form but singular in meaning, similar to 'mathematics' or 'physics'. It always takes singular verbs.
Problem
The news about the election results (was/were) broadcast nationwide.
Solution
was
'A number of' means 'several' or 'many' and is treated as plural. This is different from 'the number of', which is singular.
Problem
A number of participants (has/have) already registered for the seminar.
Solution
have
With fractions like 'half of', the verb agrees with the noun being modified. 'Cake' is singular (uncountable), so 'was' is correct.
Problem
Half of the cake (was/were) eaten by the children.
Solution
was
The subject is 'group' (singular). The phrase 'along with their conductor' is a modifying phrase that doesn't change the number of the subject.
Problem
The group of singers, along with their conductor, (is/are) performing tonight.
Solution
is
