Morphology

blowhole = blow + hole (transparent) = blow + hole

The compound straightforwardly denotes a hole through which air or gas is blown or expelled, which learners can infer from the parts.

Etymology

Blowhole comes from the words blow and hole, with blow meaning 'to push out air' and hole meaning 'a gap'. So a blowhole in rock or metal is a gap where gas or air escapes, which is why people call such gaps 'blowholes'.
