alarm (English)
Where does "alarm" come from?
The English noun 'alarm' traveled from Middle English 'alarme'[1], which was borrowed from Middle French 'alarme'[1]. The French term derives from Old Italian 'all'arme!', meaning 'to arms!, to the weapons!'[1]. This ultimately traces back to Latin 'arma', meaning 'arms, weapons'[1]. The Latin noun itself goes back to Proto-Indo-European '*h₂(e)rmos', meaning 'fitting', stemming from the root '*h₂er-', meaning 'to join'[2]. Through this ancient lineage, the semantic development shifted from 'that what is fitted together' to 'tools', then to 'weapons', and eventually into a call to arms or warning[1][2].
