Okay, up front I want to say that I'm not being a spelling cop. It's generally agreed that being able to spell or not being good at spelling has nothing to do with intelligence.
That being the case, this goes way beyond spelling, beyond grammar, beyond... well, I'm not trying to be rude and I certainly don't want a timer. But, if the word doesn't even exist, one has to wonder what word was being attempted.
So, in true liberal fashion, I checked our buddy Google.
But even Google was confused.
Perhaps you meant assimilation?
