conform
✅ 符 = tally/token + 合 = match → tally with, conform
符 originally meant a split bamboo tally — two halves issued to verify identity. 合 means to join or match. Together: the two halves fit, i.e. things conform or accord with each other.
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.
