2.1 Subject-Verb Agreement, Verb Tenses & Aspect

Key Takeaways

  • A verb must always agree with its true subject in number, regardless of intervening prepositional phrases, modifier clauses, or inverted sentence structures.
  • Compound subjects joined by 'and' take plural verbs, whereas compound subjects joined by 'or', 'nor', 'either...or', or 'neither...nor' follow the proximity rule, agreeing with the nearest subject.
  • Indefinite pronouns such as 'everyone', 'each', 'neither', and 'somebody' are strictly singular in standard ACET grammar, while 'SANAM' pronouns depend on the object of the preposition.
  • Past perfect tense ('had' + past participle) must be used to establish sequence when one past event occurred before another completed past event.
  • The subjunctive mood requires the base form of the verb in 'that'-clauses following verbs of mandate, request, recommendation, or urgency.

Subject-Verb Agreement, Verb Tenses & Aspect

The English Proficiency portion of the Ateneo College Entrance Test (ACET) heavily tests grammatical precision, structure, and formal written usage. Subject-Verb Agreement (SVA) and Verb Tense/Aspect sequence form the backbone of both Error Identification and Sentence Correction questions. ACET test-makers design items specifically to distract test-takers with long intervening phrases, inverted word order, deceptive indefinite pronouns, and complex temporal sequences.


1. Fundamentals of Subject-Verb Agreement

The core rule of subject-verb agreement is straightforward: a singular subject requires a singular verb, and a plural subject requires a plural verb. However, ACET questions rarely feature simple sentence structures like "The dog barks." Instead, test-makers insert distractors between the subject and the verb to confuse your grammatical intuition.

Intervener Phrases and Prepositional Distractors

Words or phrases coming between the subject and verb do not alter the number of the subject. Prepositional phrases (of, in, with, under, for), appositives, and participial phrases must be mentally eliminated when isolating the true subject.

  • Incorrect: The collection of rare antique manuscripts, ancient coins, and historical artifacts were destroyed in the fire.
  • Analysis: The noun phrase "of rare antique manuscripts, ancient coins, and historical artifacts" is a prepositional phrase modifying the head noun "collection." The subject is "collection" (singular).
  • Correct: The collection of rare antique manuscripts, ancient coins, and historical artifacts was destroyed in the fire.

Quasi-Conjunctions

Expressions such as along with, together with, as well as, accompanied by, in addition to, including, and no less than are prepositions, not conjunctions. They do not make a singular subject plural.

  • Incorrect: The principal, along with the senior faculty members, are attending the educational summit in Baguio.
  • Correct: The principal, along with the senior faculty members, is attending the educational summit in Baguio.
  • Rule: Only the coordinating conjunction and creates a compound plural subject when joining two items.

2. Advanced Agreement Rules and ACET Traps

Compound Subjects and the Proximity Rule

  1. Subjects joined by and: Take a plural verb ("Both the professor and the student were present"). Exception: If the two nouns refer to a single entity or unit, use a singular verb ("Peanut butter and jelly is my favorite sandwich"; "The owner and publisher of the magazine has arrived").
  2. Subjects joined by or / nor (or either...or / neither...nor): The verb agrees with the subject closest to it (the Proximity Rule).
    • Neither the lead investigator nor the research assistants were able to replicate the laboratory results.
    • Neither the research assistants nor the lead investigator was able to replicate the laboratory results.

Indefinite Pronouns

  • Always Singular: everyone, everybody, everything, someone, somebody, something, anyone, anybody, anything, no one, nobody, nothing, each, either, neither, one, much.
    • Example: Each of the candidate proposals has merits. (Do not let proposals fool you).
  • Always Plural: both, few, many, several, others.
    • Example: Several of the architectural blueprints require minor revisions.
  • Variable (SANAM Pronouns): Some, Any, None, All, Most. These pronouns can be singular or plural depending on the object of the preposition that follows them.
    • Some of the water (uncountable/singular) has evaporated.
    • Some of the documents (countable/plural) have been shredded.

Inverted Sentences and Existential There / Here

When a sentence begins with a prepositional phrase, adjectival phrase, or existential there/here, the subject appears after the verb.

  • Incorrect: Under the dense canopy of the ancient tropical forest lives several rare bird species.
  • Analysis: Locate the verb (lives). Ask: what lives? The answer is "several rare bird species" (plural subject). Therefore, the verb must be plural (live).
  • Correct: Under the dense canopy of the ancient tropical forest live several rare bird species.

3. Verb Tenses, Aspect & Temporal Sequence

Verb tense indicates when an action occurs (past, present, future), while aspect indicates how the action unfolds over time (simple, progressive, perfect, perfect progressive).

Tense / AspectStructureExample SentencePrimary Usage
Simple PresentBase verb / -s formDr. Santos conducts clinical research.General truths, habits, permanent states.
Present Perfecthas / have + Past ParticipleShe has completed three major studies since 2022.Action started in past continuing to present; unspecific past time with present result.
Past SimplePast form (-ed or irregular)The company launched the platform last year.Completed action at a specific, defined past time.
Past Perfecthad + Past ParticipleThey had finished the report before the manager asked.Action completed prior to another past action or past reference point.
Future Perfectwill have + Past ParticipleBy December, the team will have finalized the budget.Action that will be completed before a specified future time.

Past Perfect vs. Simple Past Sequence

On the ACET, when two events occurred at different times in the past, use the Past Perfect (had + past participle) for the earlier event and the Simple Past for the later event.

  • Incorrect: By the time the ambulance arrived, the paramedics already treated the injured driver on site.
  • Correct: By the time the ambulance arrived (later past event), the paramedics had already treated (earlier past event) the injured driver on site.

4. The Subjunctive Mood and Conditional Clauses

The subjunctive mood expresses wishes, hypothetical conditions, or formal demands. On the ACET, it appears in two major structures:

Mandative Subjunctive

After verbs of command, demand, insistence, recommendation, or request (insist, demand, propose, recommend, request, suggest, require, order) followed by a that-clause, use the base form of the verb (without -s or -ed).

  • Incorrect: The university committee recommended that the student representative signs the document immediately.
  • Correct: The university committee recommended that the student representative sign the document immediately.

Hypothetical / Contrary-to-Fact Conditionals

In if-clauses representing unreal or hypothetical past/present situations, use were instead of was for all persons.

  • Second Conditional (Present Unreal): If I were (not was) the department chair, I would revise the curriculum.
  • Third Conditional (Past Unreal): If the researchers had conducted additional trials, they would have discovered the anomaly earlier.
