Subject-Verb Agreement

Ensure subjects and verbs agree in number

Subject-Verb Agreement (SAT Writing)

The Basic Rule

Subjects and verbs must agree in NUMBER:

  • Singular subject → singular verb
  • Plural subject → plural verb

Simple examples:

✓ The dog runs fast. (singular)
✓ The dogs run fast. (plural)

❌ The dog run fast.
❌ The dogs runs fast.

Finding the Subject

Ignore Prepositional Phrases

Rule: The subject is NEVER in a prepositional phrase

Common prepositions: of, in, on, at, by, with, from, to, for, about

❌ The box of chocolates are on the table.
✓ The box of chocolates is on the table.

  • Subject: "box" (singular), NOT "chocolates"

❌ The students in the classroom was quiet.
✓ The students in the classroom were quiet.

  • Subject: "students" (plural), NOT "classroom"

Strategy: Cross out prepositional phrases to find the real subject

Subjects After the Verb

In questions and inverted sentences, subject comes AFTER verb:

❌ Where is the books?
✓ Where are the books?

  • Subject: "books" (plural)

❌ There is many reasons.
✓ There are many reasons.

  • Subject: "reasons" (plural)

Tip: Flip the sentence: "The books are where?" → easier to see agreement

Tricky Subjects

Indefinite Pronouns

ALWAYS SINGULAR:

  • Each, every, either, neither
  • Everyone, someone, anyone, no one, nobody
  • Everybody, somebody, anybody
  • Everything, something, anything, nothing

✓ Everyone is welcome.
✓ Each of the students has a textbook.
✓ Neither of the answers is correct.

❌ Everyone are welcome.
❌ Each of the students have a textbook.

ALWAYS PLURAL:

  • Both, few, many, several

✓ Both are correct.
✓ Few have arrived.
✓ Many were invited.

DEPENDS ON CONTEXT:

  • All, some, most, none

✓ All of the pizza is gone. (pizza = singular)
✓ All of the students are here. (students = plural)

✓ Some of the work is done. (work = singular)
✓ Some of the books are missing. (books = plural)

Compound Subjects

Joined by "AND" → PLURAL:

✓ Sarah and Emily are friends.
✓ The book and the pen are on the desk.

Joined by "OR" or "NOR" → Match the CLOSEST subject:

✓ Neither the teacher nor the students were ready.

  • "students" (plural) is closest to verb

✓ Neither the students nor the teacher was ready.

  • "teacher" (singular) is closest to verb

✓ Either the manager or the employees have the key.

  • "employees" (plural) is closest

Collective Nouns

Treat as SINGULAR when acting as ONE unit:

✓ The team is winning.
✓ The committee has decided.
✓ The family is moving to Texas.

Common collective nouns: team, group, committee, family, class, audience, jury, crowd

Titles and Names

ALWAYS SINGULAR, even if they sound plural:

The Lord of the Rings is a famous book.
✓ Twenty dollars is too much.
✓ Five miles is a long distance to walk.
✓ United States is a large country.

Confusing Situations

Relative Clauses (who, which, that)

The verb agrees with the ANTECEDENT:

✓ She is one of the students who are studying abroad.

  • "who" refers to "students" (plural)

✓ He is the only one of the candidates who has experience.

  • "who" refers to "one" (singular)

Tip: Find what "who/which/that" refers to

Phrases that Interrupt

Ignore these when finding agreement:

  • along with
  • as well as
  • together with
  • in addition to

✓ The teacher, along with the students, is attending.

  • Subject: "teacher" (singular)
  • "along with the students" is NOT part of subject

✓ The painting, as well as the sculptures, was sold.

  • Subject: "painting" (singular)

SAT Tricks to Watch For

Trick 1: Long Separation

SAT puts lots of words between subject and verb:

❌ The discovery of new planets by the telescope were exciting.
✓ The discovery of new planets by the telescope was exciting.

  • Subject: "discovery" (singular)

Strategy: Find subject, cross out everything else, check agreement

Trick 2: Plural-Sounding Singular Subjects

❌ Mathematics are my favorite subject.
✓ Mathematics is my favorite subject.

❌ The news are on at 6 PM.
✓ The news is on at 6 PM.

Other examples: physics, economics, measles, mumps

Trick 3: "One of the" + Plural Noun

❌ One of the books are missing.
✓ One of the books is missing.

  • Subject: "One" (singular), NOT "books"

Trick 4: Inverted Word Order

❌ Among the reasons for the delay was poor planning.
✓ Among the reasons for the delay were poor planning and bad weather.

  • Subject comes AFTER verb

Flip it: "Poor planning and bad weather were among the reasons"

Common SAT Patterns

Pattern 1: Indefinite Pronoun + Prepositional Phrase

❌ Each of the employees have received a bonus.
✓ Each of the employees has received a bonus.

Remember: "each" is always singular, ignore "of the employees"

Pattern 2: There is/There are

❌ There is several options available.
✓ There are several options available.

Strategy: Find the real subject after the verb

Pattern 3: Here is/Here are

❌ Here is the documents you requested.
✓ Here are the documents you requested.

Pattern 4: Subject after Verb in Questions

❌ Where is your keys?
✓ Where are your keys?

Flip to statement: "Your keys are where?"

Quick Decision Process

When you see an underlined verb:

  1. Find the subject (who/what is doing the action?)
  2. Cross out prepositional phrases and interrupting clauses
  3. Determine if subject is singular or plural
  4. Match verb to subject (singular subject = singular verb)
  5. Double-check by reading with your answer

Common Wrong Answer Traps

Matching verb to nearest noun (instead of actual subject)

  • "The bouquet of roses ARE" → wrong! Subject is "bouquet" (singular)

Treating "each/every" as plural (they're always singular)

  • "Each student HAVE" → wrong! "Each" is singular

Making verb agree with compound object instead of compound subject

  • "John or his friends IS" → wrong! Closest subject "friends" is plural

Forgetting that titles/amounts are singular

  • "Five dollars ARE" → wrong! Amounts are singular

Practice Strategy

For every subject-verb question:

  1. Circle the subject
  2. Draw a line through distractors (prepositional phrases, etc.)
  3. Determine if subject is singular (S) or plural (P)
  4. Choose verb that matches

Example:

The collection of ancient artifacts <u>was/were</u> donated to the museum.

  1. Subject: "collection" (S)
  2. Cross out: "of ancient artifacts"
  3. Singular subject needs singular verb
  4. Answer: was

Summary Checklist

When checking subject-verb agreement:

☐ Located the true subject (not in prepositional phrase)
☐ Crossed out intervening words/phrases
☐ Determined if subject is singular or plural
☐ Checked for tricky indefinite pronouns (each, everyone, etc.)
☐ Verified compound subjects (and = plural, or/nor = match closest)
☐ Remembered collective nouns are usually singular
☐ Checked for inverted sentences (verb before subject)

Remember: The SAT will try to trick you by separating the subject and verb. Always identify the subject first, ignore distractors, and make sure they agree in number!

📚 Practice Problems

1Problem 1medium

Question:

The collection of rare books, including several first editions, were donated to the library.

Which correction should be made?

A) NO CHANGE B) change "were" to "was" C) change "including" to "includes" D) change "donated" to "donates"

💡 Show Solution

Identify the subject and make sure the verb agrees.

Subject: "The collection" (singular) • NOT "books" - that's part of a prepositional phrase • Prepositional phrase "of rare books" describes the subject • Subject is still "collection" (singular)

Verb: "were" (plural)

Problem: Singular subject with plural verb ✗

Correcting: A) NO CHANGE - keeps error ✗ B) "was donated" - singular verb matches singular subject ✓ C) "includes" - doesn't fix the main verb agreement ✗ D) "donates" - wrong tense (past needed) ✗

Answer: B) change "were" to "was"

Key SAT Trick: Prepositional phrases between subject and verb are DISTRACTORS! • of rare books • including several first editions

Ignore them to find the true subject.

The collection ... was donated ✓

Common prepositional phrases to watch: • of, with, along with, together with, as well as • including, in addition to, except

These DON'T change the subject number!

2Problem 2medium

Question:

Either the manager or the employees is responsible for closing the store each night.

Which revision is correct?

A) NO CHANGE B) change "is" to "are" C) change "or" to "and" D) change "employees" to "employee"

💡 Show Solution

This involves compound subjects with "either...or" or "neither...nor"

Rule: When subjects are joined by "or" or "nor," the verb agrees with the CLOSEST subject.

Subjects: "the manager" (singular) OR "the employees" (plural) Closest to verb: "the employees" (plural) Verb should be: PLURAL

Original: "is" (singular) ✗

Options: A) NO CHANGE - keeps singular verb with plural subject ✗

B) change "is" to "are" • "are" is plural, matches "employees" • Correct! ✓

C) change "or" to "and" • Would make it "manager and employees" (both = plural) • Would also need "are" • Changes meaning unnecessarily ✗

D) change to singular • Makes both subjects singular • "is" would then work • But changes meaning (one employee vs. multiple) ✗

Answer: B) change "is" to "are"

EITHER...OR / NEITHER...NOR Rules: • Verb agrees with CLOSEST subject • Either the dogs or the cat IS... • Either the cat or the dogs ARE...

AND Rule (different!): • "And" makes compound subject plural • The cat and the dog ARE...

3Problem 3hard

Question:

Each of the students in the advanced classes have submitted their final project.

Identify all errors in this sentence.

A) "have" should be "has" only B) "their" should be "his or her" only C) Both "have" should be "has" AND "their" should be "his or her" D) NO CHANGE

💡 Show Solution

Let's check both subject-verb agreement and pronoun agreement.

Part 1: Subject-Verb Agreement Subject: "Each" (singular indefinite pronoun) • "of the students" is prepositional phrase (ignore it!) • "Each" is ALWAYS singular

Verb: "have" (plural)

Error: Should be "has" (singular) ✗

Part 2: Pronoun Agreement Antecedent: "Each" (singular) Pronoun: "their" (plural)

Error: Should be "his or her" (singular) ✗

Both need fixing!

Correct version: "Each of the students in the advanced classes has submitted his or her final project."

Answer: C) Both "have" should be "has" AND "their" should be "his or her"

Singular Indefinite Pronouns (memorize!): • Each, every, either, neither • Everyone, someone, anyone, no one • Everybody, somebody, anybody, nobody • Everything, something, anything, nothing

All take SINGULAR verbs and SINGULAR pronouns!

Each student has... his or her... Everyone is... his or her... Anybody wants... his or her...

SAT loves to trick you with:

  1. Prepositional phrase between subject and verb
  2. Plural-sounding words (like "everyone") that are singular
  3. Combined subject-verb AND pronoun errors
