is pimenta the word for pepper as in black pepper, or pepper as in bell peppers? or both?
"Pimenta" is used for black pepper, hot sauce, and other types of peppers, such as Jalapenos. The word for bell peppers, however, is "pimentão"
Except in Portugal (and the other Portuguese speaking places) where bell peppers are pimento(s). And then there is Piri-Piri...
Chili pepper, mostly. It could be used for black pepper too, but most people say "pimenta-do-reino" or "pimenta-preta" when referring to that. Bell pepper is called "pimentão".
"He eats pepper," is not something I would ever say in English. I usually say that I "use" pepper or "add" pepper to my food.
It is the same in Portuguese, but they decided to give us that sentence anyway.
The program is pronouncing pimenta as more like pim-i-enta. Is pim-i-enta the correct way to pronounce this word?
No. But the "e" can sometimes sound like that depending on accent. If in doubt, just don't say it (the "i" before the "e" that you hear) and you can't go wrong. =)
