it's the language you're missing.
You even have it in german and french...
If you haven't noticed, its the 6th most spoken language, with a potential market of more than 200 million people, in front of the german, with just 75 million (11th) and the french with 75 million(16th).
And no... Portuguese native language speakers don't speak spanish... It's the same than saying an english understands and speaks german, because of their saxonic origin.
