This question is mostly intended for bi/multilingual people but anyone with experience/opinions are welcome to respond.
I’m writing a story where my main character grew up bilingual, with English technically being their mother tongue, but they also acquired Hindi in their home environment.
My issue is with habits surrounding swearing and other uses of language. I myself am bilingual, I speak Mandarin and English fluently. I have found that, no matter what language I’m speaking, when I swear unconsciously (something happens, I’m upset, etc.) I swear in English. But, conversely, when I’m just muttering to myself or taking notes I often do so in Mandarin.
I was wondering for people who are bi or multilingual what language do you swear or mutter in? I want my character’s use of language to be fluid and natural and reflect how language is used.
I wanted to get more opinions because I didn’t organically learn Mandarin, I was taught it. So I’m curious about other people’s experience with language.
