Tri"glyph (?), n. [L. triglyphus, Gr. ; (see Tri-) + to carve: cf. F. triglyphe.] Arch.
An ornament in the frieze of the Doric order, repeated at equal intervals. Each triglyph consists of a rectangular tablet, slightly projecting, and divided nearly to the top by two parallel and perpendicular gutters, or channels, called glyphs, into three parts, or spaces, called femora. A half channel, or glyph, is also cut upon each of the perpendicular edges of the tablet. See Illust. of Entablature.
