4.8 Subject-Verb Agreement, Pronoun Case, and Verb Forms

Conventions of Usage: Agreement, Pronoun Case & Verb Forms

Core ACCUPLACER Concept: Conventions of Usage govern the grammatical relationships between words in a sentence. On the Next-Generation ACCUPLACER Writing test, these questions assess three core areas: (1) Subject-Verb Agreement, (2) Pronoun Agreement, Case, and Reference, and (3) Verb Tense, Aspect, and Mood. Questions are deliberately constructed with syntactic noise—such as long prepositional phrases, inverted sentence order, or deceptive pronouns—to distract you from the underlying grammatical core.

Mastering conventions of usage requires systematic sentence parsing. By stripping away non-essential modifiers, you can instantly identify the true subject, determine proper pronoun case, and maintain rigorous chronological verb consistency.

1. Subject-Verb Agreement Under Syntactic Stress

The fundamental rule of subject-verb agreement is straightforward: a singular subject takes a singular verb, and a plural subject takes a plural verb. However, the ACCUPLACER embeds subjects in complex syntactic structures designed to obscure agreement.

1. Intervening Prepositional Phrases and Parenthetical Modifiers

Prepositional phrases, appositives, and parenthetical expressions (along with, as well as, in addition to, accompanied by, together with) placed between the subject and the verb never alter the grammatical number of the subject.

┌─────────────────────────────────────────────────────────────────────────┐
│                     THE INTERRUPTING PHRASE TEST                        │

│                                                                         │
│  Result: "The discovery ... is remarkable."                             │
└─────────────────────────────────────────────────────────────────────────┘

• ❌ Incorrect: "The architectural blueprint for the three municipal library branches were approved by the city council."

  • Analysis: The plural noun branches is merely the object of the preposition for. The true subject is the singular noun blueprint.

• ✔️ Corrected: "The architectural blueprint for the three municipal library branches was approved by the city council."

• ❌ Incorrect: "The lead researcher, accompanied by four graduate assistants, have arrived at the field station."

  • Analysis: The parenthetical modifier accompanied by... does not create a compound subject. The subject is singular (researcher).

• ✔️ Corrected: "The lead researcher, accompanied by four graduate assistants, has arrived at the field station."

2. Inverted Word Order (Predicate Preceding Subject)

In inverted sentences—frequently beginning with prepositional phrases of location or negative adverbs (never, rarely, seldom)—the verb appears before the subject.

• ❌ Incorrect: "Beneath the ancient ruins of the acropolis lies several subterranean storage vaults."
• ✔️ Corrected: "Beneath the ancient ruins of the acropolis lie several subterranean storage vaults." (The plural subject is vaults).

3. Compound Subjects: And vs. Or / Nor

• Joined by "And": Two or more subjects joined by and almost always take a plural verb ("The geologist and the cartographer are collaborating.").
• Joined by "Or" / "Nor" / Correlatives: When subjects are joined by or, nor, either...or, or neither...nor, the verb must agree with the closest subject (The Proximity Rule).
  • ✔️ "Neither the project manager nor the field engineers were satisfied with the telemetry data." (Closest subject engineers is plural).
  • ✔️ "Neither the field engineers nor the project manager was satisfied with the telemetry data." (Closest subject manager is singular).

4. Collective Nouns

Collective nouns (team, committee, faculty, jury, audience, herd, panel) represent a single group acting in unison and take a singular verb in Standard American English.

• ✔️ "The multidisciplinary panel has reached a unanimous verdict regarding the environmental assessment."

2. Indefinite Pronoun Agreement

Indefinite pronouns do not refer to a specific person or thing. The ACCUPLACER tests your mastery of their strict grammatical classifications:

                     INDEFINITE PRONOUN TAXONOMY
                                  │
     ┌────────────────────────────┼────────────────────────────┐
     ▼                            ▼                            ▼
[ALWAYS SINGULAR]          [ALWAYS PLURAL]             [VARIABLE (SANAM)]
• Each, Every, One        • Both                      • Some
• Everyone, Everybody     • Few                       • Any
• Anyone, Anybody         • Several                   • None
• Someone, Somebody       • Many                      • All
• No one, Nobody          • Others                    • Most
• Either, Neither                                     (Number depends on
                                                       the of-preposition object!)

The Singular Indefinite Rule

Words ending in -body, -one, or -thing, along with each, either, and neither, are grammatically singular—regardless of how large the group seems.

• ❌ Incorrect: "Each of the experimental vaccine trials have yielded positive antibody responses."
• ✔️ Corrected: "Each of the experimental vaccine trials has yielded positive antibody responses."
• ❌ Incorrect: "Neither of the proposed legislative amendments were ratified by the senate."
• ✔️ Corrected: "Neither of the proposed legislative amendments was ratified by the senate."

The Variable SANAM Rule

For SANAM pronouns (Some, Any, None, All, Most), look at the noun in the subsequent prepositional phrase:

• If the object is an uncountable / mass noun, the verb is singular:
  • ✔️ "All of the contaminated soil was removed from the construction site."
• If the object is a plural countable noun, the verb is plural:
  • ✔️ "All of the geological core samples were cataloged in the laboratory registry."

3. Pronoun-Antecedent Agreement & Clear Reference

A pronoun must agree with its antecedent (the noun it replaces) in number, gender, and person, and the reference must be unambiguous.

1. Pronoun-Antecedent Number Agreement

• ❌ Formal Writing Violation: "Every prospective student must submit their portfolio prior to the application deadline."
• ✔️ Standard Formal Convention: "Every prospective student must submit his or her portfolio prior to the application deadline."
• ✔️ Best Editorial Solution (Pluralization): "All prospective students must submit their portfolios prior to the application deadline."

2. Vague or Ambiguous Pronoun Reference

A pronoun is faulty if it can refer to more than one noun antecedent, or if it refers vaguely to an entire unstated concept.

• ❌ Ambiguous: "Dr. Miller informed Dr. Chen that her research grant had been renewed." (Whose grant was renewed—Miller's or Chen's?)
• ✔️ Clarified: "Dr. Miller informed Dr. Chen that Dr. Chen's research grant had been renewed."
• ❌ Vague "This / Which": "The factory doubled its output while cutting labor hours, which caused employee burnout."
• ✔️ Clarified: "The factory doubled its output while cutting labor hours, a productivity shift that caused employee burnout."

4. Pronoun Case: Subjective, Objective & Possessive

Pronouns change form based on their grammatical function in the sentence:

│                            PRONOUN CASE CHART                           │
├───────────────────┬───────────────────┬─────────────────────────────────┤
│  SUBJECTIVE CASE  │  OBJECTIVE CASE   │         POSSESSIVE CASE         │
│ (Subjects & Pred. │ (Objects of Verb  │ (Showing Ownership              │
│    Nominatives)   │   & Preposition)  │   & before Gerunds)             │
├───────────────────┼───────────────────┼─────────────────────────────────┤
│ I, you, he, she,  │ me, you, him, her,│ my/mine, your/yours, his,       │
│ it, we, they, who │ it, us, them, whom│ her/hers, its, our/ours, whose  │
└───────────────────┴───────────────────┴─────────────────────────────────┘

The Compound Elimination Diagnostic

To determine the correct pronoun in compound structures, mentally remove the other noun and read the sentence with the pronoun alone:

• Sentence: "The department chair congratulated Dr. Alvarez and (I / me)."

• Diagnostic: "The chair congratulated I" (No!) ➔ "The chair congratulated me" (Yes!).

• ✔️ "The department chair congratulated Dr. Alvarez and me."

• Sentence: "The grant funds were divided equally between Dr. Alvarez and (he / him)."

• Diagnostic: Between is a preposition, requiring the objective case him (between you and me, not between you and I).

• ✔️ "The grant funds were divided equally between Dr. Alvarez and him."

The Who vs. Whom Master Protocol

┌─────────────────────────────────────────────────────────────────────────┐
│                     THE WHO / WHOM SUBSTITUTION TEST                    │
│  Step 1: Isolate the dependent relative clause.                         │
│  Step 2: Substitute "HE / THEY" or "HIM / THEM" into the clause:        │
│          • If "HE / THEY" (subject) works      ➔ Use WHO                │
│          • If "HIM / THEM" (object) works     ➔ Use WHOM               │
└─────────────────────────────────────────────────────────────────────────┘

• Example 1: "The candidate [who / whom] received the endorsement gave a speech."
  • Clause: [He received the endorsement] ➔ Who received the endorsement.
• Example 2: "The candidate [who / whom] the committee interviewed gave a speech."
  • Clause: [The committee interviewed him] ➔ Whom the committee interviewed.

Possessive Pronouns with Gerunds

A gerund (-ing verb acting as a noun) requires a possessive pronoun before it, not an objective pronoun.

• ❌ Incorrect: "The committee objected to him presenting preliminary data before peer review."
• ✔️ Corrected: "The committee objected to his presenting preliminary data before peer review."

5. Verb Tense Consistency, Sequence & Mood

1. Tense Consistency and Shift

Do not shift verb tenses within a sentence or paragraph unless there is a clear temporal justification.

• ❌ Shift: "The sociologist conducted field interviews, analyzes the transcripts, and documented recurring themes."
• ✔️ Consistent: "The sociologist conducted field interviews, analyzed the transcripts, and documented recurring themes."

2. Sequence of Tenses: Past Perfect (Had + Past Participle)

The past perfect tense (had discovered) is used to designate an event that occurred before another specific event in the past.

• ✔️ "By the time the search-and-rescue team arrived at the summit, the severe blizzard had subsided." (The blizzard subsided first, then the team arrived second).

3. The Subjunctive Mood

The subjunctive mood expresses hypothetical situations, wishes, or formal demands and recommendations.

• Hypothetical Condition contrary to fact: Uses were instead of was.
  • ✔️ "If the atmospheric carbon concentration were to double, global sea levels would rise significantly."
• Mandative Subjunctive (Demands/Proposals): Verbs like require, demand, recommend, insist, suggest take the base form of the verb (be, do, submit).
  • ✔️ "The university protocol requires that every laboratory technician wear protective eyewear." (Not wears).

└────────────────────┴────────────────────┴───────────────────────────────┘

• ❌ Incorrect: "The diver had swam across the channel before the fog settled."
• ✔️ Corrected: "The diver had swum across the channel before the fog settled."
• ❌ Incorrect: "The historic manuscript had laid in the museum archives for decades."
  • Analysis: Lay (to place something) requires a direct object; lie (to recline/rest) is intransitive. The past participle of lie is lain.
• ✔️ Corrected: "The historic manuscript had lain in the museum archives for decades."
