\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}.
