[khedoros]

I'm a native English-speaker, and I don't speak anything else fluently, but I speak enough of a few languages to have basic conversations in them (that is, enough to go beyond just using phrases that I learned from a book).

Every now and then, I'll forget a word in English but remember it in another language. My internal monologue tends to be English-ish (especially right now, when I'm composing a post), but if the sounds for a word are missing, the concept will fill its place...or sometimes the closest equivalent of whichever language I've been thinking about lately. I can also think almost completely in wordless concept-strings, but that sometimes feels forced.

Maybe I should mention that I learned a few words in French, German, and Spanish before I was 8, but the first time that I really studied a language in the usual sense was when I was about 12.
