  3. Reasonable: Means having sound judgment; fair and sensible. This word describes something or someone based on logic and good sense, which is the opposite of being 'Irrational'.
  4. Peaceful: Means free from disturbance; tranquil. This relates to a state of calm or quiet, not logic or reason. Thus, it is not an antonym of 'Irrational'.

Learning antonyms and synonyms is crucial for improving vocabulary and understanding word relationships in English. Antonyms provide contrast, while synonyms offer alternative ways to express similar ideas.

  • Recognizing antonyms helps clarify the precise meaning of a word by highlighting its opposite.
  • For example, understanding that 'hot' is the antonym of 'cold' helps define both terms.
  • Similarly, knowing that 'illogical' is a synonym of 'irrational' reinforces the meaning of both words as lacking logic.

When studying vocabulary for exams, try to learn not just the meaning of a word, but also its synonyms and antonyms. This approach strengthens your understanding and ability to use the word correctly in different contexts.
