For languages, I'm fluent in English (or at least pretend to be

), but I can also read and speak German at a basic level, courtesy of my mother who immigrated to the US from Germany and managed to make a little bit of it stick. I also used to be able to speak very basic Japanese when I lived in Japan, although alas, most of it has faded from disuse
Small but fun language thing! In Hawaii, we have a unique creole language called Hawaiian Pidgin, with its own accent, grammar, and slang vs standard American English. One example of how it's different from standard English is that it uses the word "one" to both literally mean one of something, but also as a substitute for the word "a", as an indefinite article. So for example...
"Eh, get one scratch ticket?" -> "Hey, want to grab a scratch ticket?"
"Eh, get
one scratch ticket!" -> "Hey, get only one scratch ticket!"
Interestingly enough, German does the same exact thing, where the word "ein" can mean either literally "one" of something, or it can just mean "a" of something:
"Lass uns ein Ticket kaufen" -> "Let's buy a ticket"
"Lass uns
ein Ticket kaufen" -> "Let's buy just one ticket"
I think it's pretty neat that Hawaiian Pidgin evolved (or re-evolved?) the same pattern, even though historically it's had very little interaction with other Germanic languages besides standard English.
