8.1 Subject-Verb Agreement, Pronoun-Antecedent Agreement & Case

Key Takeaways

  • Intervening prepositional phrases and parenthetical expressions (such as 'along with', 'as well as', and 'together with') do not alter the grammatical number of the subject.
  • When compound subjects are connected by 'or', 'nor', 'either...or', or 'neither...nor', the verb agrees in person and number with the subject closest to it (the proximity rule).
  • Indefinite pronouns like 'each', 'either', 'neither', 'everyone', 'somebody', and 'no one' are strictly singular, while 'SANAM' pronouns (some, any, none, all, most) vary based on the countability of the prepositional object.
  • Collective nouns (committee, faculty, team) require singular verbs and pronouns when functioning as a unified body, but plural verbs when individual members act independently.
  • Pronoun case is determined by syntactic function: subjective case for subjects and predicate nominatives, objective case for direct/indirect objects and prepositional objects (including compound objects like 'between you and me'), and possessive case before gerunds.

Subject-Verb Agreement, Pronoun-Antecedent Agreement & Case

Quick Answer: Under standard written English tested on WEST-B Objective 0011, verbs must agree in number with their true grammatical subjects—ignoring intervening prepositional phrases and parenthetical modifiers. Compound subjects joined by and take plural verbs, while those joined by or/nor follow the proximity rule (agreeing with the closer noun). Indefinite pronouns like each, everyone, neither, and somebody are grammatically singular. Pronoun case depends strictly on syntactic role: use subjective pronouns (I, he, she, we, they, who) for grammatical subjects and predicate nominatives; use objective pronouns (me, him, her, us, them, whom) for direct objects, indirect objects, and objects of prepositions (e.g., between you and me); and use possessive pronouns before gerunds.


1. Subject-Verb Agreement Foundations & Intervening Modifiers

The fundamental rule of subject-verb agreement states that a singular subject requires a singular verb, and a plural subject requires a plural verb. On the WEST-B, errors rarely appear in simple three-word sentences; instead, test items deliberately separate the subject from its predicate using lengthy intervening modifiers.

The Core Rule of Intervening Elements

Prepositional phrases, appositives, relative clauses, and parenthetical phrases located between the subject and the verb have zero effect on the grammatical number of the subject. You must mentally isolate and cross out these intervening structures to locate the true simple subject.

2. Compound Subjects & Conjunction Rules

Compound subjects are formed when two or more nouns or pronouns are linked by coordinating or correlative conjunctions. The conjunction used determines the agreement rule.

Compound Subjects Joined by "And"

When two or more subjects are connected by the coordinating conjunction and, they form a compound subject that requires a plural verb, regardless of the individual number of each noun.

  • Example: The principal and the counselor are attending the state symposium. (Two singular nouns joined by and = plural verb)

Exceptions to the "And" Rule:

  1. Single Unit / Collective Concept: When two nouns joined by and represent a single integrated entity or recognized conceptual unit, the subject takes a singular verb.
    • Example: Macaroni and cheese is the most popular cafeteria lunch.
    • Example: Research and development is vital for educational innovation.
  2. Identical Referent (Single Person/Role): When two titles joined by and refer to the exact same individual (indicated by a single determiner/article), use a singular verb.
    • Example: The lead researcher and department chair is presenting today. (One person holds both titles)
    • Contrast: The lead researcher and the department chair are presenting today. (Two distinct individuals, indicated by repeating 'the')

Compound Subjects Joined by "Or", "Nor", or Correlative Conjunctions (The Proximity Rule)

When subjects are connected by or, nor, either...or, or neither...nor, the verb does not automatically become plural. Instead, the verb must agree in person and number with the subject closest to the verb (the Proximity Rule).

3. Indefinite Pronoun Agreement

Indefinite pronouns refer to non-specific persons, places, or things. On the WEST-B, indefinite pronouns are among the most frequently tested agreement topics because colloquial spoken English frequently treats singular indefinite pronouns as plural.

Detailed Analysis of Indefinite Pronoun Classes

  1. Always Singular Pronouns: Words ending in -one, -body, and -thing, alongside each, either, and neither, are grammatically singular in standard formal English.

    • Example: Each of the candidates has completed the writing prompt. ('Of the candidates' is a prepositional phrase; 'Each' is the singular subject.)
    • Example: Neither of the proposed solutions is acceptable to the school board.
    • Example: Everyone in the secondary education cohorts was present.
  2. Always Plural Pronouns: Both, few, several, and many always designate more than one entity and strictly require plural verbs.

    • Example: Several of the classroom computers require operating system updates.
    • Example: Both of the instructional designs demonstrate pedagogical rigor.
  3. Variable (SANAM) Pronouns: The acronym SANAM stands for Some, Any, None, All, Most (and More). For these five pronouns, the grammatical number is determined by the noun in the modifying prepositional phrase (the object of the preposition):

    • Countable Noun Object (Plural): The pronoun represents discrete items -> Plural Verb.
    • Uncountable / Mass Noun Object (Singular): The pronoun represents a continuous quantity -> Singular Verb.
Variable PronounModifying Phrase (Object of Preposition)Count / Mass ClassificationCorrect Verb Choice
Allof the curriculum documents (plural count noun)CountableAll of the documents are archived.
Allof the funding (singular mass noun)UncountableAll of the funding has been allocated.
Mostof the chalkboard (singular count noun)Single entityMost of the chalkboard is clean.
Mostof the students (plural count noun)CountableMost of the students have arrived.
Noneof the equipment (singular mass noun)UncountableNone of the equipment is damaged.
Noneof the microscopes (plural count noun)CountableNone of the microscopes are broken.

4. Collective Nouns & Inverted Sentence Structures

Collective Nouns

Collective nouns denote a collection of individuals or units treated as a group (e.g., committee, faculty, jury, team, audience, class, staff, board, family, public, flock).

  • Unit Action (Singular - Standard on WEST-B): When the group acts as a single, cohesive entity with shared purpose, use a singular verb and singular pronouns.
    • Example: The admissions committee has reached its decision regarding fellowship awards.
  • Individual Action (Plural): When members of the group act individually, in conflict, or perform separate personal actions, use a plural verb and plural pronouns (or rewrite for clarity).
    • Example: The faculty were divided in their opinions on block scheduling.

Inverted Sentence Syntax

In standard English syntax, the subject precedes the verb. However, inverted structures place the predicate before the grammatical subject. Inversion occurs in two primary scenarios:

  1. Expletive Constructions ("There is/are" and "Here is/are"): The words there and here are never grammatical subjects; they are expletive placeholder adverbs. The true subject follows the verb.

    • Faulty: There is twenty applicants waiting in the conference hall.
    • Correct: There are [twenty applicants] (plural subject) waiting in the conference hall.
    • Correct: Here is the [revised syllabi schedule] (singular subject) for the semester.
  2. Prepositional Fronting / Locative Inversion: When an author begins a sentence with a prepositional phrase of location or direction for rhetorical emphasis, the subject is pushed after the verb.

    • Example: Behind the teacher's podium stand [three candidate portfolios] (plural subject).
    • Example: In the center of the campus courtyard grows [a historic Douglas fir] (singular subject).

5. Pronoun-Antecedent Agreement

A pronoun must agree with its antecedent (the specific noun it replaces) in person (first, second, third), number (singular, plural), and gender (masculine, feminine, neuter).

|        |                                                                                          |
|        +---> PRONOUN REFERENT:                                                                    |
|              - Non-standard / Colloquial: "their portfolio" (Number clash: singular vs plural)   |
|              - Standard Formal English: "his or her portfolio"                                    |
|              - Alternative Clean Revision: "All applicants must submit their portfolios."        |
+---------------------------------------------------------------------------------------------------+

Singular Indefinite Pronouns as Antecedents

In formal written English tested on WEST-B, singular indefinite pronouns (each, everyone, anybody, someone, neither, either) require singular possessive and personal pronouns (his, her, its, his or her), never the plural their.

  • Informal / Incorrect: Everyone must submit their final lesson plan by Friday.
  • Formal Standard English: Everyone must submit his or her final lesson plan by Friday.
  • Preferred Professional Rewrite (Plural Antecedent): All candidates must submit their final lesson plans by Friday.

Eliminating Ambiguous, Vague, and Remote Pronoun Reference

On the WEST-B Writing subtest, questions frequently ask you to identify the most effective revision for sentences plagued by faulty pronoun references:

  1. Ambiguous Reference: Occurs when a pronoun could logically refer to more than one preceding noun.

    • Flawed: When Dr. Vance met with Dean Torres, he discussed the departmental budget. (Who discussed the budget? Dr. Vance or Dean Torres?)
    • Revised: During the meeting, Dr. Vance discussed the departmental budget with Dean Torres.
  2. Vague / Broad Reference: Occurs when pronouns like it, this, that, or which refer loosely to an entire conceptual clause rather than a specific head noun.

    • Flawed: The state standardized testing software crashed repeatedly during administration, which frustrated the proctors.
    • Revised: The state standardized testing software crashed repeatedly during administration, a system malfunction that frustrated the proctors.
  3. Remote Reference: Occurs when the pronoun is placed so far from its antecedent that the syntactic connection becomes broken.

    • Flawed: The historic manuscripts were retrieved from the university archives after months of painstaking preservation, and after an extensive cross-country tour, they were cataloged. (Repeated intervening phrases weaken the referent; state the noun explicitly.)

6. Pronoun Case Matrix (Subjective, Objective, Possessive)

Pronoun case refers to the grammatical form a pronoun assumes based on its syntactic function within a clause. English pronouns operate across three functional cases:

+---------------------------------------------------------------------------------------------------+

High-Yield Pronoun Case Rules on the WEST-B

Rule 1: Compound Constructions (The Isolation Test)

Errors in pronoun case appear most frequently in compound subjects and compound objects. To determine the correct pronoun, isolate the pronoun by mentally dropping the other noun or pronoun and the conjunction.

  • Sentence: The principal presented the commendation to [Mrs. Adams and (I / me)].
    • Isolation Test: The principal presented the commendation to I? (Incorrect).
    • Isolation Test: The principal presented the commendation to me? (Correct object of preposition to).
    • Correct Sentence: The principal presented the commendation to Mrs. Adams and me.
  • Sentence: [My colleague and (I / me)] designed the mathematics diagnostic rubric.
    • Isolation Test: Me designed the rubric? (Incorrect).
    • Isolation Test: I designed the rubric? (Correct subject of verb designed).
    • Correct Sentence: My colleague and I designed the mathematics diagnostic rubric.

WEST-B Classic Trap: "Between You and Me" The word between is a preposition. Prepositions strictly require the objective case. Therefore, "between you and I" is always ungrammatical; the standard construction is strictly "between you and me".

Rule 2: Predicate Nominatives

In formal standard written English, a pronoun following a linking verb (such as is, was, were, has been) renames the subject and must be in the subjective (nominative) case.

  • Colloquial: It was her who scored highest on the exam.
  • Formal Standard: It was she who scored highest on the exam. ('She' is the predicate nominative renaming 'It')
  • Formal Standard: The representatives chosen for the task force were David and I.

Rule 3: Pronouns in Elliptical Comparisons (Than / As)

When a sentence makes a comparison using the conjunctions than or as, words are often omitted (elliptical clause). To determine pronoun case, expand the sentence by mentally supplying the missing verb.

  • Sentence: The mentor teacher has more classroom experience than [(I / me)].
    • Expanded: ...than I [have].
    • Correct: The mentor teacher has more classroom experience than I.
  • Sentence: The administrator praised Marcus more generously than [(I / me)].
    • Meaning A (Subjective): ...praised Marcus more generously than I [praised Marcus].
    • Meaning B (Objective): ...praised Marcus more generously than [the administrator praised] me.

Rule 4: Who vs. Whom (The He / Him Substitution Protocol)

To determine whether to use who (subjective) or whom (objective), isolate the clause containing the pronoun and substitute he / they or him / them:

  • If he / she / they fits -> Use who or whoever (Subject of a verb).
  • If him / her / them fits -> Use whom or whomever (Object of a verb or preposition).

Rule 5: Possessive Case with Gerunds

A gerund is a verb form ending in -ing that functions syntactically as a noun (e.g., swimming, writing, evaluating). Because a gerund is a noun, any modifying noun or pronoun preceding it must be in the possessive case, not the objective case.

  • Incorrect: The principal appreciated him arriving early for the professional development session.
  • Correct: The principal appreciated his arriving early for the professional development session. (The principal appreciated the 'arriving', which belongs to 'him' -> possessive 'his')
  • Correct: The supervisor objected to the candidate's omitting the lesson objectives.
