Since types had square and flat bottoms, and had inscriptions of thick grooves crossing the center, the shape of '〓' which appeared when they were printed was called 'Geta' because it looked like a footprint of Geta.
活字の底は四角く平らになっており中央を横切るように太い溝が彫ってあるので、それを印刷すると「〓」となり、これが下駄の歯の跡に見えることから「下駄（ゲタ）」と呼ばれた。
