I can speak, write and read fluently: English and Tagalog. I can speak and understand but not hold a lengthy conversation: Hiligaynon/Ilonggo. I can read, have a small vocabulary and poor grammar, and can understand simple conversations of Japanese and Spanish. Very very limited vocabulary in Mandarin.

That's all, I guess. The only languages I ever wanted to "collect" were programming languages, and found it a surprise I know a bit more than the staple of English and Tagalog.
