16. Glossary of Grammar Terms Used in This Guide

Several of the explanations in this guide lean on grammatical terminology that coaching-class shorthand sometimes skips over in favour of "this just sounds right." Knowing the actual term for a concept makes it far easier to diagnose an error precisely in Step 1 of the core method, rather than groping for a vague sense that something is "off." Use this glossary as a reference the first time an unfamiliar term appears in an earlier section, and revisit it during Week 1 of the drill plan in Section 9.

Antecedent. The specific noun a pronoun refers back to. In "The invigilator collected the sheets before he left," "he" has "the invigilator" as its antecedent — and if the sentence also mentioned a second male figure, the antecedent would become ambiguous, the exact problem tested in Section 3.14.

Auxiliary verb. A "helping" verb that combines with a main verb to build a tense, question, or negative — "is," "has," "will," "does," and "did" are the most common. In "She has submitted the form," "has" is the auxiliary and "submitted" is the main verb.

Collective noun. A singular noun that names a group of people or things acting as one unit — "board," "panel," "committee," "team," "jury." These typically take a singular verb in formal written English, the rule tested throughout Section 3.4.

Correlative conjunction. A conjunction that works in a fixed pair, with each half anchoring one part of the sentence — "not only...but also," "either...or," "neither...nor," "both...and." Section 3.6 and Distractor Pattern 27 both deal with errors in these pairs.

Dangling modifier. An opening descriptive phrase (usually a participial phrase like "Having revised the syllabus...") that is not immediately followed by the noun it is meant to describe, leaving it attached, illogically, to the wrong noun or to nothing at all. Covered in depth in Section 3.10.

Finite verb. A verb form that shows tense and agrees with a subject — "submits," "submitted," "is submitting." Contrast with a non-finite verb form (see below), which carries no tense of its own.

Gerund. The "-ing" form of a verb used as a noun — "Revising daily improved her accuracy," where "Revising" is the subject of the sentence, not part of a continuous tense. Gerunds are central to the idiom-correction categories in Sections 3.1 and 3.12, since many prepositions require a following gerund rather than an infinitive.

Infinitive. The "to + base verb" form — "to submit," "to clear," "to revise." The choice between a gerund and an infinitive after a given verb, adjective, or preposition is a fixed, memorised pattern in English, not a free choice, which is exactly why Distractor Pattern 16 (the Gerund/Infinitive Confusion) works as a trap.

Modifier. Any word or phrase that describes or limits another word — adjectives, adverbs, and modifying phrases and clauses are all modifiers. Section 3.10 deals specifically with modifiers that have drifted away from the word they are meant to describe.

Non-finite verb form. A verb form that does not show tense on its own and does not need to agree with a subject — gerunds, infinitives, and participles are all non-finite forms. A clause built entirely around a non-finite verb, with no finite verb anywhere, is grammatically incomplete.

Participle. A verb form used as an adjective or as part of a compound tense — the present participle ("revising," "submitting") and the past participle ("revised," "submitted"). Passive-voice constructions always require the past participle after a form of "be," which is why "was notifying" (present participle) is wrong where "was notified" (past participle) is required, as tested throughout Section 3.3.

Parallelism. The requirement that items joined in a list or by a correlative conjunction share the same grammatical form. Covered fully in Section 3.6.

Redundancy. The unnecessary repetition of the same meaning using two or more words where one would suffice — "revert back," "final and ultimate." Covered fully in Section 3.5.

Register. The level of formality appropriate to a given context. Formal exam English sits at a more formal register than everyday spoken English, which is why constructions like "kindly do the needful" or "bored of" are flagged even though they are common and perfectly understandable in casual speech — see Distractor Pattern 3, the Register Mismatch.

Squinting modifier. A modifier positioned ambiguously between two phrases, such that it is genuinely unclear which one it is meant to describe — related to, but distinct from, a dangling modifier, which has no sensible noun to attach to at all rather than two competing candidates.

Subject-verb agreement. The requirement that a verb match its subject in grammatical number (singular or plural). Covered fully in Section 3.4, including the specific triggers in the Section 12.3 reference table.

Backshift. The process of shifting a verb one tense further into the past when converting direct speech into reported speech — present becomes past, past becomes past perfect. Covered fully in Section 3.9.

Collocation. A pairing of words that native and formally trained speakers instinctively expect to appear together, even when a synonym would be grammatically valid — "take a decision" rather than "do a decision," "heavy rain" rather than "strong rain." Distractor Pattern 22, the Synonym-That-Breaks-Collocation Trap, is built directly on this concept.

Correlative structure. See Correlative conjunction above; used interchangeably in this guide to describe the fixed two-part linking patterns such as "not only...but also."

Double negative. Two negative words used in the same clause where only one is intended, which either cancels out to an unintended affirmative meaning or simply reads as ungrammatical in formal English — "hasn't hardly," "unless...not." Covered in Sections 3.8 and 5.2.
