A real word is one that is found in dictionaries.

Oh it was so kind of Dr Johnson to invent words, how did the english language get along before him? all of shakespear, written before the invention of words!

and besides, new words appear all the time, some gain favor, and become part of language, (and then, after some years, are included in dictionaries).

what do we call a collection of letters, with an agreed upon meaning, and general use, before it is a word? (that is, included in a dictionary?)
do you grok what i am saying?

i have no idea when a word becomes a word.. are the collections of letters that exist in the poem jabberwacky words? most are rarely used.. some only used in the poem and no were else. are they words or not?

i think they are... but then, what do i know?
