跳跃
tiào yuè · HSK 7
to jump
🦘 跳 jump + 跃 leap; both start with the foot radical ⻊ on the left
A two-character compound where each half means roughly to jump. The shared left-side foot radical ⻊ (from 足, foot) tags both as actions done with the feet, reinforcing the jump-and-leap sense.
跳 — foot 足 + 兆 (phonetic)
A semantic-phonetic compound. The foot radical 足 carries the meaning, since jumping is done with the feet, while 兆 (zhào) supplies the sound. Originally meaning 'to leap' or 'spring up,' it later extended to senses like 'skip over' and 'beat' (as in a pulse).
