@sara I find that my brain reaches for the equivalent word in whatever non-native language I have used most recently, and then that's all it can find again. (I.e.; I am native in English, and speak Russian and Japanese with some facility (nothing like fluent, but can get around in public if you give me time). If I have been speaking Russian recently, and I want a word in Japanese, if I remember the Russian word first it's game over, now that word is Russian until enough time passes to reset.)
