Today in the supplement of one the tamil newspapers carried a piece that the English word “Cash” came from Tamil “Kaasu”. “Kaasu” means smaller money – coins. European merchants travelling to India and China, have taken this word to Europe and it was later adapted as “Cash” in English.
The Tamil word in turn is believed to have its influence from Sanskrit word “Karsha” – which denotes weight of precious metals like Silver and Gold.
Anyway I am proud as a Tamilian that the most important word in English has its origin from my mother tongue
