Etymology
The compound "off-flavor" is a modern English formation that logically combines two native elements to describe a sensory defect. The first element, "off," derives from Old English adverbial and prepositional senses meaning "away" or "diverging from," which evolved to signify something as being substandard or not correct. The second element, "flavor," entered English via Old French from a Latin root related to "blowing" or "smell," broadening to denote taste and aroma. The compound's literal logic is transparent: a taste or smell that is "off"—that is, deviating from the expected, pleasant, or fresh standard, typically due to deterioration or an unwanted process.
Analysis
Structure: off (away, not) + flavor (taste)
off: Old English, of, æf; an adverbial particle meaning "away, from, not on/at a standard condition."
flavor: Middle English, from Anglo-Norman French flavour, alteration of Old French flaor, based on Latin flatus 'blowing'; functions as a noun meaning "distinctive taste."
