Selected source glosses provide context, not a complete modern definition inventory

From Middle English fenny, fenni (“marshy, muddy; of meat: putrid, rotten; of a person: sinful, vile”), from Old English fenniġ (“dirty; marshy, muddy, fenny”), from fen, fenn (“marsh, fen; mud”) (ultimately from Proto-Indo-European *pen- (“moist, wet; mud; swamp; water”)) + -iġ (suffix forming adjectives). The English word is analysable as fen + -y (suffix meaning ‘having the quality of’ forming adjectives).

Where this record stops

This page does not supply an independently verified sound-change sequence, first-use manuscript or complete family tree unless a cited analysis explicitly establishes one. Missing detail here is a limit of this record—not a claim that humanity knows nothing more.

An older meaning does not determine what a word must mean today. Follow the sources, preserve disagreements, and keep ancestry separate from interpretation.
