Morphology

dead + letter

The adjective 'dead' (no longer functioning) combined with 'letter' (a written text) gives a plausible inferential route to 'a written rule that no longer has effect', so part of the meaning is derivable from the parts. However, the crucial sense of 'letter' as 'the wording of a law or rule' is somewhat specialized and the phrase is a conventional legal/idiomatic usage, so a B1 learner who only knows 'letter' as a mailed message may not reliably infer the intended meaning without exposure.

Etymology

Dead letter was later used for laws and rules; one popular story says people likened a law to a letter with no life. If a rule was never used or followed, it was 'dead', so dead letter means 'a law or rule that is no longer used'.
