Etymology: The Greek verb "brúkō" meant to bite, chew, or gnash the teeth, and "brychḗ" was the noun for that grinding. English took the Greek root and added the suffix "-ism," which forms nouns for a condition or habitual state, so the word names a state of tooth grinding rather than a single act. The spelling looks odd for a Greek borrowing. Greek "brychḗ" would normally be transliterated as "brych-", which would give "brychism," but the English form uses "brux-" instead. That irregular transliteration is why the word looks so unlike its source. The medical sense is a modern one. The ancient Greeks had the verb and noun for grinding teeth, but the clinical syndrome described by this term was named in English from those classical roots, not inherited from ancient medicine.
