Homonym errors in IELTS and TOEFL writing signal weak vocabulary control — and examiners are trained to spot them.
Homonyms are words that sound the same but have different meanings or spellings: affect/effect, principal/principle, complement/compliment. Confusing them isn’t a spelling error — it’s a meaning error, which is penalised more heavily under Lexical Resource in IELTS and affects task response scores in TOEFL.
Cambridge C1/C2 Use of English (Part 1 — multiple choice cloze) regularly presents homonym pairs as distractors. Knowing which word means what in context is non-negotiable at C1 and above. This series of three exercises builds that precision systematically.
