15  Synonyms and Antonyms

15.1 Introduction

Vocabulary is a vital part of English usage and comprehension. In competitive exams like IPMAT, vocabulary questions test not just word meaning but also your ability to recognize nuances, tone, and context.
Two of the most common question types are synonyms (words with similar meaning) and antonyms (words with opposite meaning).

Building a strong vocabulary involves:
- Knowing root words, prefixes, and suffixes.
- Understanding multiple meanings of a word (denotation and connotation).
- Practicing with word families and context-based usage.

15.2 1) Synonyms

Synonyms are words that have similar or nearly the same meaning.
Example: happy → glad, joyful, delighted.
