Lewis Carroll's "Jabberwocky" was, at the time it was written, even more nonsensical than it seems today, because some of the words which Carroll invented for it have since passed into common usage in the English language. For example, chortle, invented by Carroll for "Jabberwocky" as a portmanteau of "chuckle" and "snort" - or indeed the word portmanteau itself, in its linguistic meaning.
How many other now-standard English words were originally coined by Lewis Carroll?
Note that I'm only talking about words which are now widely used, accepted as standard, and appear in most dictionaries. I know that many of the nonsense words of "Jabberwocky" (brillig, wabe, etc.) have canonical definitions as given in Through the Looking Glass itself or by Carroll, but most of them are still considered to be just that: nonsense words.
