I think it is still an open question, at least according to this [1]: > Borrowed from Medieval Latin sabbatum (or from Vulgar Latin *sambatum), from Ancient Greek σάββᾱτον (sábbāton), from Hebrew שַׁבָּת‎ (šabbāṯ, “sabbath”). It's funny cause in Romanian we're using "sâmbătă" for Saturday, which is pretty damn clause to that Vulgar Latin term "sambatum" (which makes sense, Romanian being a romance language), but our official etymological dictionary [2] gives the old slavic "sonbota" as a source.
