Alice in Wonderland.

In the second extract from Lewis Carroll’s work, Humpty Dumpty uses a word, glory, in a manner different to that which Alice would use it.  Glory is an arbitrary grouping of sounds that Humpty Dumpty uses to mean “a nice knock-down argument!”  For Alice, the signifier glory has a completely different meaning.  There is nothing in the passage, or linguistics, that indicates whether one or the other is correct.  In fact, Humpty Dumpty’s use of the word could be common in the society in which he lives (Wonderland is far away).  What it does mean, especially if this is not an isolated incident, is that he does not in fact speak English per se.
