Traditionally considered a metathesis from Proto-Indo-European *dʰewb- (“hazy, deep”), with cognates including Old Church Slavonic дъно (dŭno), Old English dēop (English deep) and Albanian det (from Proto-Albanian *deubeta). (Can this(+) etymology be sourced?) Unrelated to βᾰθῠ́ς (băthŭ́s, “deep, thick, profound”) and βένθος (bénthos, “sea depth”), despite similar semantics and superficially similar phonetics.
Alternately, cognate to Sanskrit गाध (gādha, “bottom, ford, shallows, standing-ground in water”).
Also compare the root Proto-Indo-European *bʰew- with meaning related to swelling, as in a deepening.
However, Beekes rejects Indo-European origin, based on phonetic difficulties with theories like the above, as well as θ/σσ variation displayed by the word's variant βυσσός (bussós) which is bolstered by the latter's substrate-like formation βυσσαλ- (bussal-), and assigns it to Pre-Greek instead.[1]
