reasonable and fair (idiom)

⚖️ 合(fit) + 情(feeling) + 合(fit) + 理(reason) = it fits both heart and logic

合 — 乛 (lid/roof) + 口 (mouth)
Originally a pictograph of a lidded vessel — a cover (亼) closing over an opening (口) — giving the core sense of 'come together, join, fit.' From 'fit/match' it extended to 'combine, unite, agree' and to measure-word uses. The reading hé reflects this 'joining' meaning.

情 — heart radical 忄 + 青 (qīng)
A semantic-phonetic compound. The heart radical 忄 signals that the meaning involves feelings or inner states, while 青 supplies the sound 'qing'. Originally referring to genuine feelings or emotion arising from the heart, 情 expanded to cover sentiment, affection, and circumstances or situations more broadly.

理 — jade radical 玉/王 + village 里 (phonetic)
理 is a semantic-phonetic compound: the jade radical 王 (玉) on the left signals meaning, while 里 on the right gives the sound. It originally meant the natural veins or grain in a piece of jade, then extended to 'pattern,' 'order,' 'principle,' and finally the modern senses 'reason' and 'to manage.'
