Vocabulary refers to the total set of words a person knows and uses in a language.

In BPSC TRE 4.0, vocabulary questions test your ability to understand word meanings, synonyms, antonyms, one-word substitutions, and idioms & phrases.

Strong vocabulary helps in comprehension passages, fill-in-the-blanks, and error spotting sections.

Think of vocabulary as the building blocks of language — the more blocks you know, the better you communicate and score.
