Gammadion Terms


Other Greek letter shapes are responsible for the S-shaped sigmoid colon (and the sigmoidoscope which proctologists use to scan it), the tau cross where the crossbar is at the top of the upright, and the learned gammadion for the ancient symbol composed of a cross with gamma-shaped arms, now usually called a swastika. The Greek name of our letter /F/ was digamma for the same reason. English uses “ell”, “ess”, “tee”, “vee”, and “wye” as generic shapes, too.http://www.io.com/~dierdorf/ww-17.html
