calm (English)

Where does "calm" come from?

The English word 'calm' comes from Middle English 'calm'[1], which was borrowed from Middle French 'calme'[1][3]. The French term likely derived from Old Italian 'calma'[1], though its ultimate origins remain uncertain[1][6]. One prominent theory suggests that 'calma' stems from Late Latin 'cauma' meaning 'heat of the midday sun'[1][6], which in turn traces back to Ancient Greek 'καῦμα' meaning 'heat, especially of the sun'[1][2][4]. This Greek root is formed from 'καίω' meaning 'I burn'[1][4]. The meaning of the word shifted over time from the intense heat of midday, during which people rested in quiet, to the state of quiet and stillness itself[6].

• The exact origin of the Italian word calma is disputed, with some sources noting alternative possibilities such as borrowing via an Iberian language or potential influence from Latin words for heat. [1] [3] [6]
