Etymology: Ancient Greek had the word "brukhḗ" for the grinding of teeth, a sound that could be heard in a fight or a fit of rage. It came from the verb "brúkō," which meant to bite or chew, but also to gnash one's teeth in anger. The English term "bruxism" is a modern scientific coinage built from that Greek stem and the English suffix "-ism," which forms nouns for a habitual condition or behaviour. "Bruxation" is a close synonym that uses the same stem with the noun-forming ending "-ation." The stem is not as regular as the English suffix suggests. Greek would have produced "brychism" from "brukhḗ," but the form that reached English took the spelling "brux-" instead, an irregular transliteration of the Greek. So the sound of the word has drifted from its Greek source, while its meaning, the grinding of teeth, has stayed close to the original.
