The word ‘bank’ means ‘mass’ or ‘heap’. ‘Bank’ word has been originated from the French word ‘banque’ and Italian word ‘banca’ both meaning ‘Bench’ for money exchange.
In Sanskrit, the word similar to bank is ‘bhanda’ which means collection of fund/capital.
Traditionally, the money lenders in Europe displayed coins (currencies) of different countries in big heaps on benches or tables for lending or exchanging.
Thus, the word bank means collection/fund/stock of money.
The first bank to be set up in the world was ‘Bank of Barcelona’ in Spain in 1401.
It was then, that the currency money was introduced in the world.
