1727, "ornamental groove in architecture," from French glyphe (1701), from Greek glyphe "a carving," from glyphein "to hollow out, cut out with a knife, engrave, carve," from PIE root *gleubh- "to cut, slice" (cognates: Latin glubere "to peel, shell, strip," Old English cleofan "to cleave"). Meaning "sculpted mark or symbol" (as in hieroglyph) is from 1825.
