Pre class- Differance

I am pretty sure that I could have gone my entire life without knowing anything about differance and its place in linguistics and still died a happy person. In fact, I am positive in that assertion. Nevertheless, Derrida's new word does make some form of sense.
The introduction describes differance as "an interval [that] separates two things in space as well as two in time; differance presides over such an interval, combining as it does both difference in space and deferral in time" (116). But, as Derrida notes many many times, "differance"is not a word or a concept, but just the notion of something that is not the same in time. It's like a middle ground between activity and passivity.
Derrida further explains differance through Saussure's ideas of linguistics using his notion that language is only filled with differences. Differance seems to be built on opposites and consistent inconsistencies in life which involve different notions and involves a presence of something that is not always present.
For those of you that read Calvin and Hobbes as a kid, differance is kind of like Calvinball (if I remember it correctly/understand differance so this might just be totally wrong). Calvinball was a game Calvin made up with only one official rule, you can't play it the same way twice. Each game has different rules and never can the rules be the same from game to game. Like Calvinball, differance is an abstract notion that emphasizes consistent differences in life that utilizes "a systematic play of differences" (127).
I think differance is just a fancy jargon way of explaining difference but I might be wrong.
