About
哥 consists of two 可 (kě) components stacked vertically, forming an ideogrammatic compound that originally depicted a prolonged or repeated sound. It was the primary character for "singing" in early texts. Later, the new character 歌 was created by adding the radical 欠 (to yawn) to specifically denote the action of singing, taking over that semantic role. Consequently, 哥 was phonetically borrowed to represent a different word: the colloquial term for "older brother", a word of Xianbei origin that eventually replaced earlier indigenous terms for an elder brother.
