Synonyms & antonyms
  • Synonym平静へいせいWrittenWritten word for a calm, untroubled mind or situation, leaning toward inner composure; often seen in 「平静を装う」.
  • Related落ち着くおちつくNeutralNeutral verb, the most common everyday choice: covers emotions, situations, or life settling down. Broader in range than 「沈静」, and can replace it in daily use.
  • Related静穏せいおんWrittenWritten/formal word for quiet, peaceful states — surroundings, weather, social conditions. Names a still state, without the sense of moving from motion to quiet.
  • Related静謐せいひつWrittenWritten word with a strong literary flavor: serene, hushed quiet, used for atmospheres and the state of the world rather than everyday calm.
  • Antonym高揚こうようWrittenWritten antonym: spirits or morale rising — the opposite of the calming-down sense of 「沈静」.

Say 「落ち着く」 for calming down in daily life; use 「平静」 for inner peace. In written prose, when a situation or emotion settles toward quiet, choose 「沈静」 — often as 「沈静化」.
