reek

The word 'reek' originates from the Old English verb rēocan, meaning to emit smoke or vapor, which itself is derived from a Proto-Germanic root. This ancient connection to smoke and vapor is the key to its modern meaning. Over time, the semantic focus shifted from the visible emission (smoke) to its primary sensory consequence: the strong, unpleasant smell associated with it. This evolution from a cause (smoking/vaporizing) to its most notable effect (a foul odor) provides the logical bridge to its contemporary definitions, which encompass both literal bad smells and metaphorical emanations of negative qualities.

This word is a simplex form. It is a loanword from Old English rēocan (to emit smoke or vapor, to reek), which is of Germanic origin. The functional role is that of a complete lexical root.
