Language Conventions and Vocabulary
What this domain tests
This domain covers standard English conventions and word knowledge: grammar and usage (subject-verb agreement, pronoun-antecedent agreement, verb tense consistency, modifier placement), punctuation (comma rules, semicolons, colons, apostrophes, quotation marks), capitalization, sentence structure (fragments, run-ons, parallelism), and spelling. Vocabulary items test context clues, morphology (prefixes, roots, suffixes), connotation versus denotation, and figurative language.
Concepts to master
Know that a semicolon joins two independent clauses and a colon introduces a list or explanation after a complete clause. Commas set off nonrestrictive (nonessential) elements but not restrictive ones. Dangling modifiers occur when the introductory phrase's implied subject does not match the main clause subject. For vocabulary, use the surrounding sentence's logic and contrast signals ("although," "unlike") to infer meaning, and separate a word's dictionary meaning from its emotional shading.
Traps to watch for
Items often embed a distractor that sounds formal but is wrong (e.g., inserting a comma between two independent clauses-a comma splice). Pronoun questions may hide an unclear antecedent. Vocabulary distractors frequently include a word that fits the topic but not the sentence's grammar or connotation. Watch for subject-verb agreement interrupted by a prepositional phrase ("The box of tools is heavy").
Rule of thumb
Read the sentence aloud; if you naturally pause where no punctuation is needed, or the subject-verb link feels broken, recheck. For modifiers, ask: "Who is doing the action in the opening phrase?" That noun must follow the comma.
Worked example
"Walking to school, the rain soaked Maya." The opening phrase implies Maya was walking, but the main clause subject is "rain." Correct: "Walking to school, Maya was soaked by the rain."
