Morphology

big + bang

The meaning 'a loud, sudden explosion or noise' is directly and transparently derivable from combining 'big' (large/intense) with 'bang' (a sharp sudden noise), so a B1 learner who knows both words can readily infer this sense. The adjective+noun composition is a common, cross-linguistically predictable pattern (note: the cosmological proper noun 'Big Bang' is a separate usage but does not affect the transparency of the literal noise sense).

Etymology

Big bang comes from the image of one huge explosion—a single big bang—that sent out all matter and began space and time, and that picture is why the phrase means 'the origin of the universe'.
