You and I and McWhorter

John McWhorter is an American professor of linguistics.  I enjoy his books.  I just bought one about pronouns.  He writes that his daughter, a toddler, often asked to be carried by saying,”Carry you?”.  He explains that adults often asked her those words when she was carried. So the little logic engine used the same word.  Over time she inferred that she was “me” in this instance and used the pronouns “correctly.”  Humans often learn important things outside of schools and classrooms.
