Just this morning I came across a guy called Mr Techpedia on YouTube and I was really surprised because I heard a lot of English phrases but also phrases that are in a different language or a dialect of English I’m not familiar with. It was actually really cool. It also reminds me of a time when I heard someone codeswitch from US Midwestern English to Malaysian English - there was a clear difference in word choice and pronunciation. Global/Internet English as a concept is really cool as well. I often (accidentally) adopt grammatical constructions from Global English that I believe come from that particular speaker’s native tongue.
Anyway, yeah, I love this sort of mixing of languages and I’m glad a lot of cultures are more open about mixing in English.
I am Spanish native, but the way I structure my sentence seems a google translation from chinese. People around me often don't understand the meaning, so I have to speak slower to structure my sentence in a more proper Spanish way.
I suppose languages evolve around the way their corresponding population brains work. People can still learn other languages, or be native to other languages, but there is a language way that is the best fit to some people which is related to biology.
There is no evidence for "biological inclination" towards certain languages. Take a Spanish kid and raise them on Chinese, and they'll speak it natively just fine, and vice versa.
However, natural languages evolve naturally, which means that they don't just suddenly randomly change, and that change is very gradual. So things tend to get stuck in historically-motivated local maximums that can be very different for different languages because of their different histories.
There are some plausible theories around biologically motivated language features, but this tends to be about the environment - e.g. some sounds seem to be more common in languages spoken in high-altitude areas.
Anyway, yeah, I love this sort of mixing of languages and I’m glad a lot of cultures are more open about mixing in English.
