the.com/unwritten rule
Law enforced by raised eyebrows, not courts, and somehow stricter than both.
means A norm everyone follows and enforces even though it appears in no rulebook — you only discover it exists the moment you break it.
from Straightforward compound English, built from 'unwritten' (not committed to text, from Old English writan, 'to write' or scratch marks) plus 'rule' (a guiding standard, via Old French reule from Latin regula, 'straight stick, pattern'). The phrase itself is a natural 19th/20th-century pairing — no secret backstory, just language stating plainly what it is: a rule that governs precisely because no one bothered, or dared, to write it down.
