I've been learning Spanish, Mandarin, and Korean. And when I try to speak in these languages, I always mix in Japanese particles.
Ex: Sí, el niño to la niña.
Manzanas to naranjas.
El baño ha limpio.
It's pretty funny. I don't default to my first language, I throw in Japanese. Thankfully I haven't had a reason to speak to anyone in these languages, so I haven't embarrassed myself…yet.
Does/did this happen to anyone learning multiple languages?
