Portuguese..Please let's avoid grammarfor a while
..
You know, I gave it a shot, and I went like trying to explore oxitonas, paroxitonas, and preparoxitonas..God!! Isn't that a troture?? It might seem so easy for you, but for me, to be able to know at the same time what accent to put (I don't have your weird accents anyway
), and also how to prunouce them...C'est pas de la tarte!!!
Back to the topic..I personnaly can't say what language is the most difficult to learn..I believe that with time, patience and determination..You can do whatever you want.. :-)
