A friend shared this with me and I thought I would share with y'all
I have a hobby of tracking the origin of words. So let me tell you the origin of the word karatsi in Swahili.
Starting in the 1500s when the Portuguese started calling on the ports of Dar es Salaam and Mombasa, every time a ship from Portugal pulled into port, all the Portuguese who were waiting for the ships would row out to the arriving ships shouting : Cartas! Cartas! Cartas! What they received - if anything - were rolled pieces of paper! You see the word "cartas" means "letters". The marooned Portuguese were starved for news from Portugal and could not wait to
read their letters! Receiving and distributing letters was an important ritual
among the Portuguese. The on-looking Africans eventually referred to all paper as "cartas" which eventually became "karatasi" in Swahili".
