Eh... When people ask me, I only say j speak Russian,French and English because all else is negligible. I honestly feel sometimes like I have no "native" tongue because in no language I have significant mastery. I'd love to speak English like kleinbl00 , or Russian like Posner. I understand it all, but can't express myself fully in that manner. It kinda sucks. Master of none....
Speak two languages: bilingual. Speak three languages: trilingual. Speak one language: American. I am an American. ;-) They killed the Russian class in my High School when I was in 4th grade. My mother arranged for me to study Russian with the teacher's daughter that summer. I can only say that High School Russian is a hard damn thing for a 4th grader to learn during the summer. Growing up, Spanish was predominant but not only is it a dialect disavowed by both the Mexican and Castillian school, it's a dialect used by the locals to isolate the white folx. Spanish was actually a lot easier to understand in Los Angeles because it wasn't intended as exclusionary. I studied German in High School but any language you don't use regularly is a language you lose. I've never been proficient in anything but English. I can understand some spoken German and Spanish but not well enough to bother attempting to converse in it.
That's still hella impressive for an American! Especially considering how good you speak English. I spoke to similarly eloquent people in Russian and I'm always just jealous of the rich vocabulary, expressions and all they can transmit in a sentence. "Understanding" is not the same as being able to come up with the fancy words on the spot.
