[quote=zmjezhd Mad is a troublesome word. Many folks use it as a synonym for angry. This upsets some.

I'm not sure why that would be though. In my Oxford dictionary, one of the definitions of mad is "angry" and in my Webster's, one of the definitions is "enraged".

I wonder what is the cut-off for acceptance of a modification of definition. If the modification happened in the 20th century, is it not as acceptable as if it happened in the 15th?
