From Proto-Balto-Slavic *źū́ˀs; related to Latvian zivs, Old Prussian suckis (“fish”), from Proto-Indo-European *dʰǵʰu-;[1] cognate with Ancient Greek ἰχθῡ́ς (ikhthū́s), Old Armenian ձուկն (jukn, “fish”).
Since *dK- regularly yielded *iKt- in Greek (compare ἰκτῖνος (iktînos), ἑκατόν (hekatón)), Proto-Indo-European *d- as opposed to *dʰ- must be reconstructed, encouraging a connection with the root *deǵʰ- (“liquid?”); compare Old Irish deug (“drink, draught, potion”), Lithuanian dažaĩ (“paint, dye”). A similar semantic path can be observed in ūdra (“otter”) from *wed- (“water”) [2]
