The character 胳膊 (gēbo), meaning "arm", is formed through a combination of semantic and phonetic components. Both characters share the radical 月 (a form of the "flesh" radical, 肉), on the left side, which categorically indicates that the word is related to a part of the body. The right side of each character, 各 (gè) in 胳 and 尃 (fū) in 膊, primarily serve as phonetic hints to suggest pronunciation, though they may have loose associative meanings. Together, they form a single, concrete concept where the bodily radical provides the core meaning and the combined characters create a specific, dissyllabic word for "arm".
