Like I speak English and Portuguese, learning Dutch, and (not doing it for the sake of a primarily English-speaking community) but I will often switch between the two, like saying “Bom dia/Oi” to someone or “Tchau!”
I may also falar assim and I don’t do it to show off, it’s just comfortable pra mim. I will mix in a few português words. (Not exactly like this but YKWIM, maybe).
Being English, I’m stubbornly monolingual (aside from some leftover schoolboy French), so when I was invited to a Sikh wedding I was genuinely amazed by all the guests just flowing between English and Punjabi as if they were the same language.
It’s not just them, a lot of people across the world speak a mix of english and their native tongue.
Even seen philipino subs coming to the reddit front page? They usually start with an English phrase and end in tagalog.
Was the wedding fun? Anything funny happen?
