"Triglyph" Natural Recordings by Native Speakers
A triglyph is a Greek architectural term that refers to a module in a metope of the Doric order, specifically in a frieze. It consists of a rectangular space or panel between two triglyphs. Triglyphs are typically indicated by slight grooves or channels on the surrounding metopes, which form the vertical member's vertical ridge, or the "filler."
