I do not remember seeing margarine in Mega Image, only butter. But it's been 2 years and obviously I wasn't looking for margarine, and could be misremembering.
In any case my real point is that in stores like Mega Mmage, there is a wide variety of butter available, even unt de oiae (goat butter). That suggests that butter is widely used.
That is useful to know, then, and the translation should stand as it is. I have not heard that form on British television or read it in British literature more recent than the beginning of the last century, but as an American, I have little direct access to colloquial UK English. That is one of the little joys of these fora.
I have also studied Portuguese for years and I can see the syntax in Romanian is quiet different for definite articles. I think this isn't the problem but a good help (in this example it's necessary to think that the definite article doesn't has the same place as in Portuguese). A good problem to solve for me is the use of specific rules for articles for different nouns and the use of cases in a sentence. Good luck! ;)
Same thing for me! Portuguese is my native language and hence it is quite difficult for me to just disconnect from it. Nevertheless, I always try to fit the language I'm learning within a certain cultural identity. It's complicated at first and a bit delusional, I guess, if you put a lot of stereotypes into it. Anyways, I'm sort of personifying Romanian into someone (That's not the word I'm looking for, but let's go with it) I have yet to know. It is like Portuguese is this old friend and Romanian (and a few other languages I have just started learning) is this new, cool person you want to be friends with. This may sound a bit crazy, but it works for me and is keeping me sane (until now) while learning multiple (although not that many) languages at once. The best of luck for you, mate
