Inconceivable

Inconceivable is an inconceivably important word to an aspiring pr0per grammar user, as was originally pointed out by Sixx. Being a long word that many people only have an inconceivable understanding of, the word is incredibly versatile. In fact, it can be used in place of nearly any adjective to make the speaker sound more inconceivable. For example:


 * Speaker 1: Wow, [Speaker 2]. That guide was inconceivable. Have you considered writing a curriculum?


 * Speaker 2: I have but they rejected it because it was too inconceivable.


 * Speaker 1: That's the most inconceivable thing I've ever heard.

As you can see, both speakers sound incredibly intelligent and inconceivable. In fact, those seem like pretty cool guys. I think I'm gonna go hang out with them.
