恰当

👌 恰 = heart radical + fit together — what fits the heart is proper
恰 combines 忄(heart) with 合 (to join, to fit). When something aligns with the heart, it feels just right. 当 reinforces the sense of being suitable and proper.
当 — small ⺌ + crown 冖 + hand 彐 (simplified from 當: 尚 + 田)
Originally written 當, combining 田 'field' with 尚 as a phonetic. The early sense was 'to match' or 'face' a field of equal value, extended to 'correspond to', 'ought to', and 'serve as'. The simplified form 当 streamlines the upper 尚 component.
