Stating the obvious is also known as a "forelitive" statement. Derived from the saying "for real?"
When someone says
something that points out the obvious, it would be considered a forelitive statement. It also can be a
generic response to someone else who says
something about a subject. A forelitive response.
A forelitive statement: i.e. "Be careful when you watch her." Obviously, if you're taking care of someone, you're going to be careful. Especially, a
baby. Do you think if it wasn't
said, would you NOT be careful?
A forelitive response: STATEMENT: "I'm trying my hardest." RESPONSE: "Well,
everyone tries their hardest."
Basically, a meaningless response that doesn't give any consolation to the statement.
