1, Spanish. Which I already speak fluently.
2, Brazilian Portuguese. Sound very different than European Portuguese.
3, Classical Arabic.
4, German. Was originally my 3rd language before Spanish, I'm still somewhat conversational in it, but it's not what it used to be.
5, Slavic languages. Especially western Slavic like Croatian or Czech.
I also speak Hungarian thanks to my grandparents, and some Greek thanks to my other grandparents.
They are OK but not languages I'd ever recommend anyone to try to pick up. Especially not Hungarian, and especially not if your mother tongue is English.
