duster

The word 'duster' is a transparent compound formed within English from its native Germanic elements. Its core, 'dust', descends from the Proto-Germanic dunstuz, which is related to concepts of vapor and fine particles, and further back to the Proto-Indo-European root dheu-, meaning 'to rise in a cloud, to smoke, to scatter'. The agent suffix '-er' is one of the most productive in English, directly inherited from Old English '-ere', itself from Proto-Germanic -ārijaz. The literal logic of 'duster' is perfectly clear: it is 'a thing that deals with dust'. Over time, its application expanded from a person who dusts to the primary modern meaning of a cloth or tool for removing dust, and later to protective garments and agricultural equipment that handle dust-like substances.

Structure: dust (fine, dry particles) + er (agent suffix) dust: From Old English 'dūst', meaning fine, dry particles of earth or other matter. It functions as the core noun root. er: A Germanic agent suffix, used to form nouns denoting a person or thing that performs an action. It functions as a derivational suffix.
