I was wondering besides linqg which are some good free resource.for Portuguese I need to know the conjugations and and finer grammar points
I wouldnât recommend you learn French, Spanish and Portuguese at the same time, specially the last two. You will certainly mix them together and getting to speak what we can âportunholâ because these two languages are very close. We can communicate with each other (Spanish and Portuguese speakers) fairly well.
Going to the resource, I donât know but if you want to know some conjugation go only to the very basic since even I donât know a good part of conjugations.
