I was reading some Spanish grammar stuff, and it mentioned the word "cuyo" as basically meaning "whose". I've literally never heard of this word before, and I've studied Spanish since middle school and even spoken it with people conversationally, so I'm very confused.
It seems like this would be a really common word, but I swear I've never encountered it before. Is it regional, or rarely used, or have I just managed to overlook it for years?
Yeah. I also don't think whose comes up that often in English either. You wouldn't say "the person whose shirt is white" but rather "the person with a white shirt" for example. I think it's the same in Spanish and Portuguese
Yeah, I guess it's mostly used as a question in English and that's it.
