2.2 Grammar, Usage & Mechanics
Key Takeaways
- The written exam tests standard edited American English grammar through sentence-correction and error-identification items.
- Common targets include subject-verb agreement, pronoun-antecedent agreement, parallel structure, verb tense consistency, and modifier placement.
- Commonly confused word pairs (its/it's, affect/effect, principal/principle, fewer/less) appear as usage distractors.
- Punctuation and mechanics — comma splices, run-ons, apostrophes, and semicolons — are tested because they change legal meaning.
- Error-identification items ask you to find the one underlined-style segment containing an error or to select the best-corrected version of a sentence.
Why Grammar Is Scored, Not Assumed
Within the English Language Proficiency domain (about 25% of the written exam), grammar, usage, and mechanics are tested directly. The exam uses two recurring item styles drawn from standardized-test conventions:
- Error identification — a sentence is shown with several segments; you choose the one segment that contains a grammatical error, or choose "No error."
- Sentence correction — a sentence (or part of it) is shown; you choose the answer that fixes the error while preserving the original meaning most clearly and concisely.
Grammar is scored because syntax carries legal meaning. A misplaced modifier or an ambiguous pronoun can change who did what to whom — unacceptable in a sworn record. An interpreter who cannot parse standard English at speed will mis-render the structure even if individual words are known.
The High-Frequency Targets
| Category | What is tested | Quick check |
|---|---|---|
| Subject-verb agreement | Verb matches subject in number | Find the true subject, ignore intervening phrases |
| Pronoun-antecedent | Pronoun matches its noun in number/gender | Each pronoun must have one clear antecedent |
| Parallel structure | Items in a series share grammatical form | Lists and comparisons must match form |
| Verb tense | Consistent, logical sequence of tenses | Watch unjustified tense shifts |
| Modifier placement | Modifiers sit next to what they modify | Hunt dangling/misplaced modifiers |
| Pronoun case | Subject vs. object vs. possessive | "who/whom," "I/me," "its/it's" |
Agreement, Parallelism, and Modifiers
Subject-Verb Agreement
The verb must agree with the grammatical subject, even when words come between them. In "The list of exhibits is on the clerk's desk," the subject is list (singular), not exhibits. Collective nouns (jury, court) usually take a singular verb in American usage: "The jury has reached a verdict."
Pronoun-Antecedent Agreement
Every pronoun needs one unambiguous antecedent that matches in number. "Each juror must cast their vote" is widely accepted, but exam keys often expect "his or her vote" for strict agreement with the singular each.
Parallel Structure
Items joined in a series or comparison must share grammatical form. Faulty: "The witness was asked to remain calm, to tell the truth, and answering fully." Correct: "...to remain calm, to tell the truth, and to answer fully."
Modifier Placement
A dangling modifier has no logical word to attach to. Faulty: "Reviewing the file, the motion was denied." The file was not reviewed by the motion. Correct: "Reviewing the file, the judge denied the motion."
Commonly Confused Words and Usage
Usage items hinge on word pairs that sound alike or look alike but differ in function. The exam uses these as quiet distractors inside otherwise correct sentences, so you must spot the misuse, not just the meaning.
| Pair | Distinction | Correct example |
|---|---|---|
| its / it's | possessive vs. "it is/has" | The court issued its ruling. |
| affect / effect | usually verb vs. usually noun | The ruling will affect the effect of the statute. |
| principal / principle | main/chief vs. a rule | The principal issue is a principle of due process. |
| fewer / less | count nouns vs. mass nouns | Fewer jurors, less evidence. |
| who / whom | subject vs. object | Who testified? To whom was it addressed? |
| than / then | comparison vs. time/sequence | He arrived later than noon, then left. |
| lay / lie | place something vs. recline | Lay the file down; the witness will lie down. |
A usage error in a charging document or instruction can be argued to change meaning, which is why the written exam treats these as substantive, not cosmetic.
Punctuation and Mechanics
Punctuation is tested because it changes legal meaning. A comma splice joins two independent clauses with only a comma; a run-on (fused sentence) joins them with no punctuation at all. Both are marked wrong on error-identification items. Correct options use a period, a semicolon, or a comma plus a coordinating conjunction.
- Comma splice (wrong): "The defendant waived the right, the hearing proceeded."
- Corrected: "The defendant waived the right**;** the hearing proceeded."
- Restrictive vs. nonrestrictive: "Witnesses who lied were charged" (only the lying ones) versus "The witnesses**, who lied,** were charged" (all of them lied). The commas change the legal scope.
- Apostrophes: "the juror**'s** notes" (one juror) versus "the jurors**'** notes" (several). Possession can identify a party, so placement matters.
- Semicolons correctly link closely related independent clauses or separate list items that already contain commas.
For sentence-correction items, prefer the answer that is grammatically correct, unambiguous, and concise, and that does not change the original meaning. An option can be grammatically clean yet still wrong if it alters who did what.
Identify the grammatical error: "The list of approved interpreters were posted outside the courtroom."
Which revision best corrects this sentence while preserving meaning: "Reviewing the transcript, the objection was sustained"?
Choose the sentence that uses commonly confused words correctly.
Which sentence is punctuated to mean that ALL of the jurors were dismissed?
