Homonyms have always messed with me. Every since I was young, they would beat me over the head and the spell checker hates me now, but I have come to enjoy them.

Anyway, here goes. Everyone knows the words incite and insight... well, I just think that it is extremely interesting that one could use a word like insightful and mean both meanings at the same time... why don't we have a system in language in which we can convey double entendre without "just hoping" that the listener/reader gets the meanings.

Example:
Jo's speach was insightful: a new paradigm of American culture that provocated an immediate reaction.
