How Tanganyika got its name.

Conventional wisdom says Tanganyika is derived from Swahili for 'sail'. I have another theory. Tanganyika has a very Tamil sound. And it feels like it must have been formed from 'Thanga Neekka' or 'Where gold is removed'. It's highly possible that Tamil explorers discovered gold deposits near the lake and concentrated their energies on neekifying thangam or mining out gold. So the waterway to the gold deposits became Thanga-neeka and over a period of time it morphed into the Swahili Tanganyika.

And why do I feel this is credible? Ancient Tamils did a lot of trading with East Africa. And evidence is fast emerging that much of South India's gold came from Africa. Also, Tanzania is the third big gold producer of Africa.
