Morphology

saint + Elmo's + fire

This is an eponymic, specialized name for an electrical discharge; knowing 'saint' and 'fire' (and an unfamiliar proper name 'Elmo') does not allow a B1 learner to infer a visible blue/violet electrical phenomenon. The meaning is encyclopedic and culturally specific rather than compositionally derived from its parts, so prior exposure or explanation is required.

Etymology

Saint Elmo's fire may come from old sailors who saw a blue glow on ship masts and wires during storms and thought it was the light of Saint Elmo watching over them, so they called the glow a 'fire' even though it was not a real flame. Today Saint Elmo's fire means the bright electric glow you can see on pointed objects like masts or wings during a storm.
