learn Spanish. it is easy. I taught myself to speak enough to convey what I needed, all within a week of watching you tube videos while doing cardio and speaking the language here and there with my wife.
then you can speak and understand Portuguese well enough to have a basic conversation
while Portuguese does have some words that are hard to pronounce for me, it's way easier then I'd imagine English being for others.
The thing with the portuguese vs english language is, one english word can be applied to 10 different meanings/concepts, wereas one concept in portuguese has 10 different words to describe it.
I am portuguese, born and raised, and have trouble understanding spanish, like in a normal conversation. And thrust me, the spanish have a even harder time, understanding us. You must be truly gifted, or have psychic habilities, to speak and understand street talked portuguese, when you have "spanish for dummies" language level.
Not to mention that you have several spanish dialects, Castellano, Catalán, Gallego, and the nightmare Vasco. And then you have the South American gems.
