blow-dryer

The word 'blow-dryer' is a modern English compound noun, transparently constructed from its functional components. The verb 'blow' has ancient Germanic roots, descending from Proto-Indo-European bʰleh₁- ("to blow, swell"), which evolved into its current sense of moving air. 'Dry' originates from Proto-Germanic drūgiz, related to the concept of solidity and lack of liquid. The suffix '-er' is the standard agentive marker in English. The compound logically names the device by its primary dual function: it 'blows' air in order to 'dry' hair, with the '-er' suffix identifying it as the tool that performs this combined action. This practical, descriptive formation reflects the straightforward naming conventions for mid-20th century household appliances.
