English Grammar - Synonyms and Antonyms

Select the most appropriate synonym of the given word: PERFIDIOUS


Options:

  1. Honest
  2. Faithful
  3. Treacherous
  4. Loyal

Right Answer: Treacherous

The word 'perfidious' is an adjective that describes a person who deliberately breaks faith or betrays trust. It comes from the Latin 'perfidia', meaning faithlessness. A perfidious ally is one who secretly works against you while pretending loyalty. Among the given options, 'treacherous' carries exactly this sense of betrayal and deceit, so it is the correct synonym. The other three choices are antonyms rather than synonyms: 'honest', 'faithful' and 'loyal' all describe trustworthy behaviour, which is the opposite of what 'perfidious' means. Hence the correct answer is Treacherous.
