to combine
🧩 組む (team up) + 合わせる (fit together) = 組み合わせる, to combine
組む means to assemble or team up, and 合わせる means to match or fit together. Joined, they form 組み合わせる, meaning to combine parts into one arrangement.
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.
