I'm Portuguese. I'm fluent in French, and minimally capable in Italian. Without formally studying Spanish, I can understand spoken and written Spanish, as well speak it (albeit poorly). I can't understand most words in spoken Catalan, and can't speak it altogether. Catalan is a close enough language that I can understand its written form, but it is not as close to Spanish as Spanish is to Portuguese.
