Well, it's like I say-- there's a grey area between the two. Also, the difference can be one of degree, with the prank call being the more general or normative term and the crank call being a more extreme form. But people who draw a sharp distinction between harmless "humor" and the malice of telephone harrassment would see the two in terms as I just explained them. I wouldn't be surprised if someone didn't pop up and argue the idea that you can use either word to mean the same kind of annoying behavior.drei_lengua said:Thanks foxfirebrand. Good to hear from you again. I have always known these words to be interchangeable but I guess they aren't.
