5.2 Vocabulary Building: Synonyms, Antonyms, Idioms & Phrases

Vocabulary Building: Synonyms, Antonyms, Idioms & Phrases

A robust vocabulary is critical for excelling in the verbal section of the CIL MT examination. Vocabulary questions appear in diverse formats: direct synonym and antonym selection, sentence completion (single and double fillers), contextual vocabulary in reading comprehension, phrasal verb application, and one-word substitution. Rather than attempting to memorize isolated word lists alphabetically, top scorers utilize morphological etymology—breaking words down into Latin and Greek roots, prefixes, and suffixes.
