From earlier blurre, probably an alteration of blear, from Middle English bleren, from Old English *blerian (attested in āblered (“made bare, made bald”)), from Proto-West Germanic *blaʀjan, from Proto-Germanic *blazjaną (“to make pale”), from Proto-Germanic *blasaz (“pale”). Compare Scots blore, bloar (“to blur, cover with blots”), Low German bleeroged (“blear-eyed”). More at blear.

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.
