war (English)

Where does "war" come from?

The English word 'war' descends from Middle English 'werre', which came from Late Old English 'werre' or 'wyrre'[1][3]. This moved through Anglo-Norman and Old Northern French 'guerre' or 'werre', derived from Medieval Latin 'werra'[1][3][4]. The Medieval Latin term was borrowed from Frankish '*werru', meaning 'confusion' or 'quarrel'[1][2][3][4]. Ultimately, this traces back to the Proto-Indo-European root '*wers-', meaning 'to mix up, confuse, beat, thresh'[1][3][4]. During the Middle English period, this term gradually displaced native Old English words for armed conflict like 'beadu'[1].
