Vocabulary: Synonyms, Antonyms, and Word Use
The concepts to understand
Vocabulary questions test more than memorised lists. You need denotation (dictionary meaning), connotation (positive, negative, neutral flavour), register (formal, informal, technical), collocation (which words naturally accompany which), and the ability to use a word correctly in a sentence. Word formation matters too: prefixes, suffixes, roots, and parts of speech derived from a common stem.
Traps that appear in questions
- Near-synonyms with different connotations. Frugal and stingy both concern spending, but one is approving and the other critical.
- Overlapping but non-interchangeable words. Refuse and deny differ in object: you refuse an offer, deny an accusation.
- Antonym traps. The opposite of transparent in a figurative sense is opaque, not dark.
- Look-alike pairs. Affect/effect, complement/compliment, principal/principle, stationary/stationery, emigrate/immigrate.
- Choosing by sound. Candidates pick a familiar word rather than the one that fits the sentence's grammar and sense.
Worked example
Select the word closest in meaning to meticulous: (a) careless (b) scrupulous (c) hasty (d) ordinary.
Meticulous means showing great attention to detail, so (b) scrupulous is correct. Note that (a) and (c) are antonyms, and (d) is merely unrelated. When two options seem plausible, test each in a sentence with the same grammatical frame; only one will fit naturally.
Rule of thumb
Learn words in families and in context: record the word, its part of speech, one collocation, and one sentence of your own. A word you can use is a word you know.
