Barbarism versus barbarity
There is a significant difference in meaning between barbarism and barbarity. Both denote some absence of civilization, but the word "civilization" itself has several different senses, one the opposite of barbarism, the other the opposite of barbarity.
On the one hand civilization may refer to the scientific, artistic, and cultural attainments of advanced societies, and it is this sense that figures in the meaning of barbarism. The English word barbarism originally referred to incorrect use of language, but it is now used more generally to refer to ignorance or crudity in matters of taste, including verbal expression: “The newspaper would never allow such barbarisms“.
On the other hand, civilization may refer to the basic social order that allows people to resolve their differences peaceably, and it is this sense, that is civilization as opposed to savagery that figures in the meaning of barbarity, which refers to savage brutality or cruelty in actions: “The reports of the terrorists' barbarity in the way they treated their hostages has been worse than anyone could have anticipated.“
