re: #650 Aceofwhat?
Language is tricky as hell. We don’t really, really understand how kids learn it. Or adults, for that matter. There are a lot of non-intuitive things about language acquisition, such as vocabulary size as a child having no relationship to vocabulary size as an adult.
It’s fascinating stuff. For example, it’s easier for a Cantonese speaker to learn Thai than Mandarin, even though there is no real relationship between Cantonese and Thai and a very strong one to Mandarin.
