Yes about the intonation of the word. The difference is that that "really" would mean "mom", "stupid", "really", "nothing" according to the tone. Some embarrassing mistakes.

Well, the previous poster's examples of "really" could be defined like this, based on interpretation of their intonation:

"Really?": Convince me; "Really!": I'm indignant on your behalf; "Really hungry": exceptionally [hungry]; "Really good": average.
