dust

dust: [OE] The notion ultimately underlying dust seems to be that of ‘smoke’ or ‘vapour’. It goes back to a prehistoric Indo-European base *dheu-, which also produced Latin fūmus and Sanskrit dhūma- ‘smoke’. A Germanic descendant of this, *dunstu-, picks up the idea of a cloud of fine particles being blown about like smoke, and is the basis of Norwegian dust ‘dust’ and duft ‘finely ground grain’, German duft ‘fragrance’ (from an earlier Middle High German tuft ‘vapour, dew’), and English dust.

dust (n.)

Old English dust, from Proto-Germanic *dunstaz (cognates: Old High German tunst "storm, breath," German Dunst "mist, vapor," Danish dyst "milldust," Dutch duist), from PIE *dheu- (1) "dust, smoke, vapor" (cognates: Sanskrit dhu- "shake," Latin fumus "smoke"). Meaning "that to which living matter decays" was in Old English, hence, figuratively, "mortal life."

dust (v.)

c. 1200, "to rise as dust;" later "to sprinkle with dust" (1590s) and "to rid of dust" (1560s); from dust (n.). Related: Dusted; dusting. Sense of "to kill" is U.S. slang first recorded 1938 (compare bite the dust under bite (v.)).
