Forms
brū f (genitive singular brūwe, nominative plural brūwe)[1] Plural also brūa, brūwa, genitive plural brūwena, brūna, dative plural brūwum.[2]
Etymology
It is inherited from Proto-Germanic *brūwō (“eyebrow”), which goes back to Proto-Indo-European *h₃bʰrúHs (“brow”).[1] Orel sets the Proto-Germanic noun beside Old Norse brún (“eyebrow”), whose ⟨n⟩ he takes from the plural stem.[3] Holthausen and Orel compare the same old word for the brow outside Germanic: Ancient Greek ὀφρῦς (ophrûs), Sanskrit भ्रू (bhrū́), Lithuanian bruvìs, Proto-Slavic *bry and Middle Irish brúad, a dual form.[4][3] Köbler traces it to the root Proto-Indo-European *bʰrū- (“brow”) (Pokorny 172).[5] Bosworth and Toller send the reader on to brǣw (“eyelid”).[2]
Hogg and Fulk class brū historically as an ō-stem and note that the nominative singular seems not to be recorded.[6] The late glossaries usually have the plural ⟨brūwa⟩, rarely ⟨brūa⟩, and the dative plural ⟨brūwum⟩: a glide was most likely inserted in hiatus, after which the noun could be taken for a regular noun of the type of stōw.[6]
Earliest recorded meaning
The first dated record is in Riddle 40 of the Exeter Book, copied in the second half of the tenth century: the speaker says “ne ic breaga ne bruna brucan moste”, “I could make use of neither eyelids nor brows”.[7][8] Bosworth and Toller read bruna there as the genitive plural of this word.[2]
Semantic evolution
Old English used the word both for the eyebrow and for the eyelashes, and in the glossaries it renders Latin cilium, supercilium and tautones.[2][9] Sweet and Holthausen give the eyelid as a further sense.[9][4] The Durham Ritual glosses Latin palpebris meis “my eyelids” with brūum mīnum.[10] Etymonline holds that “eyebrow” was probably the first meaning.[11]
The word lived on as Middle English broue, plural broues, brouen, from about 1300, now brow, and by the early fourteenth century it also meant the ridge above the eye.[11]
