I heard a version that the word comes from the Spanish barriga - belly. In the Middle Ages, moneylenders and wealthy merchants were called so, because they had a big belly - an indicator of wealth.
There is no final and precise version of the origin of the word "huckster". There are only theories, different interpretations in dictionaries. Presumably it comes from the Turkic word "profit" and means a hike or trip. Also, there is a theory that the word comes from the Russian word "gift". It is believed that the huckster is also a buyer of stolen things. In the Moscow "thug" jargon, such a buyer is called a "bag", in the prisons of the southern provinces - "blatak", in the Western Territory - "guroyu". As for jargon, the word "huckster" is used in the meaning of "an old thief who abandoned his former dangerous craft and replaced it with a less risky one."
According to one version it comes (presumably) from profits, from Turkic .; Wed: tour., Crimean-Tat. baryš "peace, reconciliation", Kirg. baryš "hike, trip"; Wed also ukr. barish, belor. darling. According to another hypothesis, the source is Russian. words - in Chuv. * parǝš "gift", tat. bireš, tour. -veriš.
