I am just curious... I know the internet is not where you go for proper grammar, spelling, etc. & I am definitely not a "grammar nazi", but where did the misspelling of the just-used term (i.e. "definately") come from and how did it become so prevelant? Don't believe me? Take a moment to search the LPSG forums for the (incorrectly spelled) term "definately". I guess my personal theory is that it is just evidence of the power of the internet itself. Perhaps "definitely" is one of those terms that people use all the time in conversation ("like", "totally") but rarely (pre-internet) would have occasion to use in written form. Now that everyone uses the term in email, chat, blog, postings, etc. the common misspelling is mimicked to the point of becoming the accepted form...just a thought.
