Old English bærnan

Old Norse brennabor.

Middle English brennen

English burn

From Middle English barnin, bearne, beerne, beornen, berne, bernen, birne, burne, burnen, bærnen, which arose via the metathesis of branne, brennen, brennyn, brynne, from Old English beornan, biernan, birnan, byrnan, from Proto-West Germanic *brinnan, from Proto-Germanic *brinnaną (“to burn”), from Proto-Indo-European *bʰrenw-, present stem from *bʰrewh₁- (“to boil; to brew”). The East Midland forms were heavily influenced by Old Norse brenna, brinna (“to burn”). Doublet of brew.

The late metathesis of East Midland brin- to birn- (and subsequently burn-) parallels the phonological development of bird and dirt from brid and drit. As this metathesized form became the Chancery Standard, it completely displaced the semantic functions and weak conjugation paradigm of the native Old English bærnan (weak), alongside the surviving remnants of byrnan (strong).
