Most of the words I've encountered in written Portuguese appeared to be either Spanish or French, or visually a combination of the two. It's another child of Latin, alongside Spanish, Italian, French, Romanian, and others. I don't know the history and I don't intend that Portuguese is a child of the two, only that it is another product of the Latin echo chamber by way of its two most visually apparent influences.

I've never had any purposeful encounters with any of the languages you mention, though I would certainly like to!
