These are loan words in Hungarian borrowed early from an Iranian  language and reflect the early wanderings of the Hungarian (or Magyar) people who originally lived in western Siberia. These two words have cognates in modern Persian vazaq "frog" and sad "hundred" although the Iranians that the Proto-Hungarians encountered were probably Scythians or closely related Sarmatians. They also illustrate how languages sometimes borrow common ordinary words from other languages and not just technical, scientific or cuture-specific words.

Hungarian also contains loans from Slavic and Turkic languages, even Germanic (barna "brown", homar "lobster", kulyo "bullet" - German Kugel and nyak "neck’).  :)

Some ethnolinguistic scholars may indeed argue for a pre-Slavic, Iranian origin to Croat peoples before the 6.cent.AD Slavic invasion of Balkan SE Europe which took its historic place sometime after Iranian Scyths, Finno-Ugric Royal Scythians, Iranian Cimmarians & Sarmatians, Teutonic E&W Goths, Uralic-Altaic Huns, Turkic Avars, and Turkicized or Turkic Bulgars could each in turn have willy-nilly brought Oriental names & Iranian vocabulary to this population-ravaged frontier.  Furthermore, said Magyar invasion c. 900 precedes Turkic Cumans in 12.cent.AD and Altaic-Tungusic Mongols one war-torn century later, who all had similar contact with various Iranian cultures not only situated across infinite sands & steppes of C. Asia, but also here & there throughout a far greater, pan-Caucasian region than today.
