Left radical is
'leg/foot' (足). Right radical is a character found only in Chinese
meaning 'raised/break clear', which here acts phonetically to express
'leap high'. 'Dance' is an associated meaning. Henshall
suggests taking the right radical as a simplification of 'pass' (通),and
mnemonic: 'Dance, using feet in passing.'
