角
jiǎo · HSK 2
horn
🐂 Pictograph of an animal horn; jiǎo sounds like 'jow'
角 began as a drawing of a ridged ox horn, with the curved lines marking its segments. From 'horn' it extended to anything horn-shaped: a corner, an angle, or a bugle (号角).
角 — pictograph of a horn
角 is a pictograph of an animal's horn, with early oracle-bone forms clearly showing the curved, ridged shape of a horn. From 'horn' it extended to mean corner, angle, and by metaphor a role or part (as in a stage role). The reading jiǎo covers most of these senses.
