弟dì

ns unchanged from the traditional, picturing a bent figure that originally represented a younger brother and later took on the meaning of "younger brother". Today 弟 is used in everyday language to refer to a younger brother and appears in words like 兄弟 (brothers). It also functions as a phonetic component in characters such as 第 (ordinal prefix), 剃 (to shave), and 娣 (a concubine).
