Most of those are clearly Indian, but plenty surprised me — bandana, catamaran, cheetah, cot, cummerbund, dinghy, jungle, and pundit.
“Pandit” is the origin of pundit, a Hindi honorific often given to Nehru, for example.
My favourite, not listed, is “nabob”, as in a rich potentate or corporate titan, a coffee brand, and nattering nabobs of negativism. Other than the coffee, it seems to have slipped out of standard usage since the 70s. It was originally from “nawab”, a Mughal provincial governor, who typically lived in a level of considerably grandeur.
I was most struck by typhoon, which I had assumed of Chinese origin, and atoll.
I thought typhoon was Chinese as well, but its etymology is odder than I could’ve imagined.
I say “typhoon” comes from Chinese.
