>Because polymorphism is not the same thing as multiple inheritance.

It would fall into composition. Having said that, as mentioned in the other message, it would still be interesting to get the terminology for multiple inheritance. I still have this image in my mind. When I took that course, there was a slide with all the terminology being related to OOP. I am pretty sure those where single word only. Next to them, in the following slide, we were able to get more info such as the generic overview of what that single OOP word means.
