Morphology

skull + and + crossbones

The phrase literally names its constituents — a skull and crossed bones — so a learner who knows 'skull', 'and', 'cross' and 'bones' can directly infer it refers to that depicted symbol. Its conventional use as a warning of danger or poison is culturally widespread but rests on transparent, compositional imagery rather than an idiomatic shift.

Etymology

Skull and crossbones shows a human skull above two crossed bones; one popular story says people used that picture on old graves and on pirate flags to stand for 'death'. So the image became a clear way to warn people of 'danger' or 'poison'.
