tupi

The word comes from Portugese/Spanish, the origin is 'nanas' which the Tupi people in Brazil used [1].

The interesting part, is that despite the fact that the language is officially dead, almost all Brazilian geography (mountains, beaches) and partially cities have until today a tupi name.

The Tupi field discovered off Brazil makes about 100,000 a day and best-case contains a few years of American oil production total.

In the 18th century, the Marquis of Pombal implemented a program to extinguish usage of Tupi as the national language and replace it with Portuguese.

That way everyone would have to learn a new language:) old tupi I guess is as good and any Extinct Language.

Etymology for abacaxi: Borrowed from Old Tupi ibakatí.

In Brazil there are also manuscripts in the native's, non-written language (tupi) codified by catholic priests dating back to XVI, but those are better understood because the language was kept alive up to the late XIX.

I've always found the diameter:circumference ratio so much more natural for thinking about geometry that when I used to program regularly I had a macro called 'tupi' which would expand to (2 * pi) at compile time.

>Other scholars[who?] claim that the name is derived from the Tupi word amassona, meaning "boat destroyer".

Here in Brazil, where the fruit originates, the most common name for it is "abacaxi", It's supposed to come from Tupi-Guarani family of languages and means "fruit with a nice smell".

I would vote for "old tupi", an extinct Tupian language which was spoken by the aboriginal Tupi people of Brazil and in the early colonial period, Tupi was used as a lingua franca throughout Brazil by Europeans and aboriginal Americans.

The most common term is "ananas" or some close variation, from the extinct Old Tupi language of what is now Brazil, which was a common trade language in the region in the colonial period.

There are other Tupi-Guarani words that made it to other languages, like Açaí, Piranha, Capybara,...

So the actual origin is from the Tupi-Guarani linguistic families [2].
