reek: [OE] Reek originally meant ‘smoke’ (Edinburgh was called Auld [old] Reekie because of its smoky chimneys, not because it smelled). The word came from a prehistoric Germanic *raukiz, which also produced German rauch, Dutch rook, Swedish rök, and Danish røk, all meaning ‘smoke’. It is likely that it was related to Latin ructāre ‘spew out’ (source of English eructate [17]), in which case the etymological notion underlying reek ‘smoke’ is of something ‘belching’ out. The English sense ‘bad smell’ emerged in the 17th century.
