歌手
かしゅ · kashu · JLPT N3 · noun
singer
🎤 歌手 = song + hand: 手 marks a skilled doer, so a song-doer
歌 (ka) means song and 手 (shu) means hand, but at the end of a word it marks a person skilled at something, as in 運転手 driver and 選手 athlete. So 歌手 is the person whose craft is song.
歌 — 哥 (phonetic 'gē') + 欠 (open mouth)
A semantic-phonetic compound. The right side 欠 depicts a person with an open mouth, supplying the meaning of singing or vocalizing. The left side 哥 gives the sound 'gē'. Together they form the verb and noun for 'song' or 'to sing'.
手 — pictograph of a hand with five fingers
手 is a pictograph showing an open hand with fingers and a wrist. Early bronze and oracle bone forms clearly depict five splayed fingers, which simplified over time into the modern shape. It keeps its original meaning of 'hand' and also serves as a radical in many characters related to hand actions.
