Grammar, Verb Tense & Subject-Verb Agreement
Key Takeaways
- Subject-verb agreement requires matching singular subjects with singular verbs and plural subjects with plural verbs, regardless of intervening prepositional phrases.
- Compound subjects joined by 'and' take plural verbs, whereas subjects joined by 'or' or 'nor' agree with the subject closest to the verb.
- Pronouns must agree in gender and number with their antecedents; singular indefinite pronouns like 'everyone' and 'each' require singular pronouns.
- Pronoun case depends on syntactic function: nominative for subjects and subject complements, objective for direct/indirect objects and objects of prepositions.
- Verb tenses must remain consistent throughout sentences and passages, shifting only to reflect actual changes in time frame.
Grammar, Verb Tense & Subject-Verb Agreement
The HSPT Language subtest heavily measures your mastery of standard written English syntax, clause structure, and grammatical logic. Among all tested domains, rules governing subject-verb agreement, pronoun-antecedent agreement, pronoun case, and verb tense consistency form the core foundation of error-identification questions. Mastering these rules requires moving beyond "what sounds right" in casual speech to recognizing formal structural requirements.
1. Subject-Verb Agreement Principles
The fundamental rule of subject-verb agreement is straightforward: singular subjects require singular verbs, and plural subjects require plural verbs. However, HSPT test writers actively construct sentences designed to trick your ear by inserting distracting words between the subject and the verb.
Intervening Prepositional Phrases and Modifiers
The most common trap on the HSPT is the intervening prepositional phrase. Prepositional phrases (such as of the students, in addition to the teacher, along with the books) placed between a subject and its verb do not change the number of the subject.
- Incorrect: The box of heavy books were left near the doorway.
- Correct: The box [of heavy books] was left near the doorway.
- Analysis: The subject is the singular noun box, not the plural noun books inside the prepositional phrase.
Common prepositions that introduce distracting phrases include: of, in, with, along with, together with, as well as, in addition to, and except. Always cross out intervening phrases to isolate the true subject.
Compound Subjects: "And" vs. "Or / Nor"
When connecting multiple subjects, the conjunction determines whether the resulting subject is singular or plural:
- Joined by "And": Compound subjects joined by and almost always take a plural verb because they combine multiple entities.
- Example: The teacher and the student are reviewing the exam results.
- Joined by "Or" or "Nor": When subjects are joined by or, either...or, neither...nor, or not only...but also, apply the Rule of Proximity. The verb must agree in number with the subject closest to it.
- Example 1: Neither the coach nor the players were ready for the game.
- Example 2: Neither the players nor the coach was ready for the game.
Indefinite Pronouns
Indefinite pronouns do not refer to a specific person or thing. Standard written English categorizes them into three distinct agreement groups:
| Agreement Category | Indefinite Pronouns | Verb Agreement Rule | Example |
|---|---|---|---|
| Always Singular | each, every, everyone, everybody, someone, somebody, anyone, anybody, no one, nobody, either, neither, one | Requires a singular verb | Each of the candidates has five minutes. |
| Always Plural | both, few, many, several | Requires a plural verb | Several of the answers were correct. |
| Variable (SANAM) | some, all, any, none, most | Agrees with the noun in the prepositional phrase | Some of the cake was eaten. / Some of the cookies were eaten. |
2. Pronoun-Antecedent Agreement
A pronoun must agree with its antecedent (the noun it replaces) in both number (singular vs. plural) and gender (masculine, feminine, neuter).
Singular Indefinite Antecedents
On the HSPT, singular indefinite pronouns (such as everyone, each, anybody) require singular possessive pronouns (his, her, or its), not the plural their.
- Informal / Conversational: Everyone must hand in their test paper.
- HSPT Formal English: Everyone must hand in his or her test paper.
- Tip: If a sentence specifies gender, use the matching singular pronoun (e.g., "Each of the female athletes completed her project").
Collective Nouns as Antecedents
Nouns referring to a group (such as team, committee, jury, family, class) take singular pronouns when acting as a unified single unit.
- Example: The committee announced its decision yesterday afternoon. (The committee acts as one body).
3. Pronoun Case
Pronoun case refers to the form a pronoun takes based on its grammatical function in a sentence. The three cases are subjective (nominative), objective, and possessive.
| Case | Singular Forms | Plural Forms | Grammatical Function |
|---|---|---|---|
| Subjective | I, you, he, she, it, who | we, you, they, who | Subject of a verb or predicate nominative |
| Objective | me, you, him, her, it, whom | us, you, them, whom | Direct object, indirect object, object of preposition |
| Possessive | my/mine, your/yours, his, her/hers, its, whose | our/ours, your/yours, their/theirs, whose | Indicates ownership or relationship |
Common HSPT Pronoun Traps
- Compound Subject/Object Test: To determine the correct pronoun in a compound construction (e.g., Marcus and I/me), temporarily drop the other person to test the sentence.
- Sentence: The principal invited Marcus and (I / me) to the assembly.
- Test: "The principal invited me" (Correct) $\rightarrow$ The principal invited Marcus and me.
- Subject Complements (Predicate Nominatives): Following linking verbs (such as is, was, were, became), standard English requires subjective case pronouns.
- Formal Correct: It was she who answered the phone. (Not her).
- Who vs. Whom: Use who as a subject (replaceable by he/she/they); use whom as an object (replaceable by him/her/them).
- Example: Whom did you invite to the seminar? (You invited him).
4. Verb Tense Consistency and Sequence of Tenses
Verb tense indicates when an action takes place. Sentences and passages must maintain a consistent temporal perspective unless a change in time is logically indicated.
Avoiding Unnecessary Tense Shifts
Do not shift from past to present or present to past without a logical reason.
- Shift Error: Marcus walked into the classroom and takes his seat.
- Corrected: Marcus walked into the classroom and took his seat.
Sequence of Tenses: Past Perfect
The past perfect tense (had + past participle) expresses an action completed in the past before another past action occurred.
- Example: By the time the bell rang (simple past), the students had finished (past perfect) their assignments.
5. Sample HSPT Error-Identification Practice
Analyze how these principles appear in standardized HSPT question lines:
Question: Identify the error in the sentence below: (A) A list of instructions (B) for the upcoming science projects (C) were posted on the bulletin board. (D) No error.
Analysis:
- Subject: list (singular)
- Prepositional Phrase: of instructions for the upcoming science projects (ignore during subject-verb check)
- Verb: were posted (plural $\rightarrow$ ERROR)
- Correction: Change were posted to was posted. Correct answer is (C).
Identify the correct verb form for the following sentence: 'The collection of rare coins and antique stamps ________ sold to a private collector at auction.'
Which pronoun correctly completes the sentence: 'At the awards ceremony, the principal presented certificates of achievement to Sarah and ________.'
Select the option that maintains correct pronoun-antecedent agreement: 'Each of the female finalists brought ________ own portfolio to the interview.'
Choose the option with proper tense sequence: 'By the time the headmaster arrived at the auditorium, the choir ________ three songs.'
