I just say my Spanish fluent. I can have a conservation, but it will have a lot of pauses as I try to remember a word. Certainly not usable at an academic level.

I was graced by parents who don’t know their own language very well. Google Translate’s more reliable, so there is a lot of vocabulary I don’t know simply because it’s never been brought up in my family.

I just consider English my main language. I feel bad for the immigrants who were raised not even knowing their language though. Met a few.
