The kanji 稜 is a 形声文字 (keisei moji), a phono-semantic compound character. The phonetic component is 禾 (kome - rice, grain), and the semantic component, which provides the meaning, is 山 (yama - mountain). It originally depicted the edges or corners of a mountain, which is the intersection of two surfaces. Over time, it came to represent edges and corners in general.
