injury: [14] Etymologically, an injury is something ‘unjust’. It comes via Anglo-Norman injurie from Latin injūria, a noun use of injūrius ‘unjust’, which was a compound adjective based on jūs ‘right’ (source of English just). Its original meaning in English was ‘wrongful action’, and it was only gradually that the notion of ‘harm’ (which had actually been present in the word from classical Latin times) began to come to the fore. => just[injury etymology, injury origin, 英语词源]
