First found in the Armenian–Latin dictionary of Polish-Armenian Stefanus Roszka, quoting a work known only to him, therefore probably written in the Aṙtial (Transylvania) dialect milieu which was spoken by the Armenian diaspora in Romania, Hungary and Poland, some of whom immigrated from Crimea. See also թուխու (tʻuxu) and լոսդի (losdi) with a similar philological context. From this dictionary, the word was adopted in the literary language as the standard designation of the sturgeon. Considered a word of unknown origin. Compare Romanian turpac (“beluga (Huso huso)”), Ukrainian турпа́к (turpák), Polish turpak (“Russian sturgeon, Acipenser gueldenstaedtii”), apparently borrowed by a semantic development from dialectal Russian турпа́к (turpák, “one-year-old calf; two-year-old bull calf; young beluga; young sturgeon; magpie”)․ Probably all ultimately from Turkic: compare Karakhanid [script needed] (torpi), Siberian Tatar то̄рбаҡ (tōrbaq, “young calf”). Note also Georgian თართი (tarti, “sturgeon”).
