Language Conventions and Vocabulary
What this domain tests
This domain covers the mechanics and word knowledge that make writing clear: grammar and usage, punctuation, capitalisation, spelling patterns, sentence structure, and vocabulary in context. Questions typically ask you to choose the correct form, fix an error, or select the word that best fits a sentence's meaning and tone. Accuracy is the point - the exam rewards precise control and the ability to explain why a form is correct.
Core rules and concepts
- Sentence completeness. Every sentence needs a subject and a finite verb and must express a complete thought. Watch for fragments and run-ons; fix run-ons with a period, semicolon, or conjunction.
- Agreement. Subjects and verbs agree in number; pronouns agree with their antecedents. Watch intervening phrases ("The box of tools is heavy").
- Punctuation. Commas separate items, set off non-essential clauses, and follow introductory elements. Semicolons join independent clauses; colons introduce lists or explanations. Apostrophes mark possession and contractions, not plurals.
- Modifiers. Place modifiers next to what they describe; dangling modifiers occur when the described noun is missing.
- Vocabulary in context. Use surrounding clues (definition, contrast, example, cause) and check connotation as well as denotation.
Worked example
Sentence: *"Walking to school, the rain soaked my jacket."
Reasoning: The introductory participial phrase "Walking to school" must modify the sentence's subject. As written, it modifies "the rain," which cannot walk - a dangling modifier. Revision: "Walking to school, I was soaked by the rain." Now the subject "I" performs the walking. The fix is structural, not a comma change.
Traps that cost marks
- Trusting sound over grammar ("between you and I" is wrong; use "me").
- Using apostrophes for plurals ("tomato's" for more than one tomato).
- Joining independent clauses with only a comma (comma splice).
- Choosing a synonym with the wrong connotation for the sentence's tone.
- Missing subject-verb agreement when a phrase separates subject and verb.
