'Phenomenon' might be a bit much, but is there a name for when you are learning or practicing a foreign language, and slip into a different foreign language as a sort of support?
Like, you're an English speaker trying to say something in German but instictively use a Spanish word for something, even though that makes no sense. It's almost as if anything other than your native language is just all grouped together.
Edit to Add: As I'm new to this group I just noticed some friendly non-answers were removed because they don't answer my specific question. So I'm adding that I'm also interested to know if this happens to any of you as well.
