Origin of the word

Origin of the word

The word bank was borrowed in Middle English from Middle French banque, from Old Italian banca, from Old High German banc, bank "bench, counter". Benches were used as desks or exchange counters during the Renaissance by Florentine bankers, who used to make their transactions atop desks covered by green tablecloths.^[12]
One of the oldest items found showing money-changing activity is a silver Greek drachm coin from ancient Hellenic colony Trapezus on the Black Sea, modern Trabzon, c. 350–325 BC, presented in the British Museum in London. The coin shows a banker's table (trapeza) laden with coins, a pun on the name of the city. In fact, even today in Modern Greek the word Trapeza (Τράπεζα) means both a table and a bank.
Another possible origin of the word is from the Sanskrit words (ब्यय) 'byaya' (expense) and 'onka' (calculation) = byaya-onka. This word still survives in Bangla, which is one of Sanskrit's child languages. ব্যায় + অঙ্ক = ব্যাঙ্ক . Such expense calculations were the biggest part of mathematical treatises written by Indian mathematicians as early as 500 B.C.
