From Latin fabrum, accusative of faber 'id.'
Dissimilated from Proto-Italic *fafro- 'id.' From Proto-Indo-European *dhHbh-ro- "craftsman."
Still in use as the surnames Fabro, Fabros.
Western Vulgar Latin: Portuguese fabro, Italian fabbro; Eastern Vulgar Latin: Aromanian favru, Romanian faur; Sardinian: frau, frab, frabbu
Armenian: darbin "smith"
If fabro and its cousins are etymologically related to a smattering of words found in Baltic (Lithuanian dabà "nature"), Slavic (Old Church Slavonic podoba "ornamentation"), and Germanic (Gothic gadof "fitting," "right"), then Beekes (1996) believes all of these words must be borrowed from a non-Indo-European language with a root *dhabh-.
