哥哥
gēge · HSK 1
brother
👦 哥 repeated = older brother; 哥 = 可 (phonetic 'kě') + 可 stacked
The character 哥 doubles 可 (kě), giving the sound 'gē'. Chinese kinship terms often reduplicate for familiarity, so 哥哥 (gēgē) is the everyday word for an older brother, while a single 哥 can also be a friendly term for an older male.
