Borrowed from a Germanic language, probably Gothic 𐌷𐌻𐌰𐌹𐍆𐍃 (hlaifs) (Proto-Germanic *hlaibaz) which has the root final 𐍆 (f) (phonetically probably [ɸ]) in the nominative, vocative, and accusative singular and 𐌱 (b) (phonetically probably [β]) in the oblique case forms. The fricative was replaced by the labial stop *b since Proto-Slavic did not have labial fricatives. Alternatively it may be from Old High German hleib.
Scholars do not agree whether *xlě̀bъ originally referred to leavened or unleavened bread.[who exactly?]
