残疾

♿ 残 = remnant/damaged + 疾 = illness; together: lasting bodily damage
残 carries the sense of incomplete or harmed (same 残 as in 残留 leftover), and 疾 is a classical word for sickness or affliction. The compound names a permanent impairment rather than a passing illness.
残 — 歹 (bones/death) + 戔 (small/cut, phonetic)
A semantic-phonetic compound: 歹 (bare bones, death) gives the meaning of harm or ruin, while 戔 (two 戈 spears, suggesting cutting) supplies the sound. Originally meant to injure or destroy, later extended to 'remnant, leftover' — what remains after damage.
