If I may coin a word...
Let it be hereby known and henceforth remembered that I do on this day Tuesday, February 28th of the year 2006 of the Common Eraa, coin the word componential and its definition, made up of several or more components.
EDIT: After typing the word into the Google search engine, I find that it is already a word. HOWEVER: It is not a commonly or widely used word, and therefore, if I tell people I coined it, they may well believe me. And if they choose to look it up, or if they know already, and can prove me wrong, then I can just say, "Yeah, I know, I just like to say it's mine. I don't really know who coined it. But it's a really cool word, isn't it?"
