Technically, jaguar is from the Portuguese, but originally a native language word from a tribe in South America where the wild felines live.

My point is, I am not annoyed by words being pronounced in different ways in different parts of the world. I think that is only natural that there would be regional differences in pronunciation.

What does kind of annoy me is that one class of people in one country would think they have the ONLY correct way to pronounce a word - and believe the rest of the world is wrong.
