Sense: adjective/1
All four words describe a lack of emotional disturbance, but they differ in scope and style. 'Calm' (adjective/1) is the most general — it describes the absence of strong emotions like anger, worry, or excitement, especially in a stressful situation. 'Relaxed' is less intense: a relaxed person feels no tension, whereas a calm person may feel tension but controls it. 'Peaceful' often extends beyond a person's feelings to describe the overall environment — a peaceful room or a peaceful nation — while 'calm' stays closer to the individual's emotional state. 'Composed' is more formal and suggests deliberate self-control: someone who is composed has actively arranged their feelings. For example: 'He stayed calm during the argument' (emotionally stable despite stress), 'She felt relaxed on the beach' (no stress at all), 'The garden was peaceful' (environment), and 'The CEO remained composed during the press conference' (deliberate poise under scrutiny).

Etymology
The word 'calm' entered English from Old French 'calme', which came from Italian 'calma' and ultimately from Late Latin 'cauma', meaning 'heat of the day' — a time when the midday heat made everything still. The original Latin word was borrowed from Greek 'kauma' (heat). The meaning shifted from 'hot, still part of the day' to 'stillness' in general, and later to 'emotional peace'. The silent 'l' was added in the 1500s by scholars who wrongly thought the word came from Latin 'calor' (heat) or 'calmum'.
