PSAT GRAMMAR RULES:
Subject-verb agreement
The subject and verb must agree in number (singular or plural).
Collective nouns can be singular or plural depending on context.
Indefinite pronouns (e.g., everyone, each) are usually singular.
Pronoun-antecedent agreement
Pronouns must agree with their antecedents in number and gender.
Be cautious with collective nouns and indefinite pronouns.
Ensure clarity by placing pronouns close to their antecedents.
Verb tense consistency
Maintain the same tense throughout a sentence or related sentences.
Use past tense for completed actions and present tense for current actions.
Be mindful of shifts in time that may require a change in tense.
Parallel structure
Use the same grammatical structure for items in a list or series.
Ensure consistency in verb forms, phrases, and clauses.
Parallelism enhances clarity and readability.
Comma usage
Use commas to separate items in a list, after introductory phrases, and before conjunctions in compound sentences.
Use commas to set off non-essential information.
Avoid comma splices by not joining two independent clauses with just a comma.
Semicolon and colon usage
Use semicolons to connect closely related independent clauses.
Use colons to introduce lists, explanations, or quotes.
Ensure the clause before a colon is a complete sentence.
Apostrophe usage
Use apostrophes to indicate possession (e.g., the dog's bone).
Use apostrophes in contractions (e.g., can't for cannot).
Be careful with plural nouns that do not require an apostrophe.
Sentence fragments and run-on sentences
A sentence fragment lacks a subject or verb and does not express a complete thought.
Run-on sentences occur when two independent clauses are improperly joined.
Use punctuation or conjunctions to correct these errors.
Modifier placement
Place modifiers close to the words they modify to avoid confusion.
Avoid misplaced modifiers that can change the intended meaning.
Use clear and precise language to enhance clarity.
Commonly confused words (e.g., their/there/they're, its/it's)
Understand the different meanings and uses of commonly confused words.
Practice using them in context to reinforce correct usage.
Pay attention to homophones that sound alike but have different meanings.
Active vs. passive voice
Use active voice for clarity and directness (e.g., The dog chased the cat).
Passive voice can obscure the subject and make sentences less engaging (e.g., The cat was chased by the dog).
Prefer active voice in most writing situations.
Coordinating and subordinating conjunctions
Coordinating conjunctions (for, and, nor, but, or, yet, so) connect equal parts of a sentence.
Subordinating conjunctions (although, because, since) introduce dependent clauses.
Use conjunctions to create complex and compound sentences.
Dangling and misplaced modifiers
A dangling modifier lacks a clear subject and can confuse the reader.
Misplaced modifiers are incorrectly positioned, leading to ambiguity.
Revise sentences to ensure modifiers clearly relate to the intended words.
Comparative and superlative adjectives
Use comparative adjectives to compare two items (e.g., taller, smarter).
Use superlative adjectives to compare three or more items (e.g., tallest, smartest).
Be mindful of irregular forms (e.g., good, better, best).
Idiomatic expressions and prepositions
Understand common idiomatic expressions and their meanings.
Use prepositions correctly to indicate relationships in time and space.
Be aware of idiomatic phrases that may not translate directly.
