Neologisms:

On the "isn't a word" thread, Sasha points out:

What irks me is how people just make up neologisms rather than use the good traditional words that are perfectly available. Plus, rather than learn proper English, they mangle the language in ways that "simplify" grammar and spelling, and this is drifting into the written language too. They don't even recognize good grammar and spelling and traditional words if they see them written on the page!

In fact, just the other day, when I tried to use perfectly good English, to wit: "Hwæt! Wé Gárdena in géardagum þéodcyninga þrym gefrúnon, hú ðá æþelingas ellen fremedon" -- no one knew what I was talking about!

Damn kids.
