語源

Uncertain. The term possibly derives Proto-Indo-European *bʰébʰrus (perhaps via Proto-Italic *fefr-), with the raising of the initial vowel to /i/. Alternatively, the term may derive directly from a PIE form of the shape *bʰi*bʰr- (perhaps via Proto-Italic *fifr-). According to De Vaan, due the varying usage of /e/ and /i/ as reduplication vowels in PIE, it is impossible to decide between either form. Moreover, the o-stem of the Latin term conflicts with the u-stem of the PIE form. It is perhaps possible that there existed a PIE o-stem term *bʰebʰros or *bʰibʰros. Doublet of beber.
