From the same root (the Greek “gregoros”) that brought us the name Gregory; Greer is said to be a shorter version of Gregor. But whether it’s used for a girl or a boy, this name means “watchful,” and you better believe your little Greer is watching your every move … and waiting for the most embarrassing possible opportunity to retell it.
There's hardly a good nickname for Greer.
