夗 ('to turn over in sleep / lie curled') is archaic and not used independently in modern Chinese. It survives as the phonetic in 怨 (resentment), 宛 (winding / as if), 婉 (graceful / tactful), 碗 (bowl), and 苑 (a garden / park).

Archaic. One older tradition reads 夗 with a different tone in the 'curled / winding' sense; both feed its large phonetic family.
