page 53, elements of nonsense

My understanding of what 'elements of nonsense' are sentences that do not make sense logically but make sense in the format of a sentence. These are the elements of nonsense that I found in Jabberwocky by Lewis Carroll on page 53.

- 'twas brillig, and the slithy toves'
-'did gyre and gimble in the wabe'
-'all mimsy were the borogoves-
-'and the mome raths outgrabe'
-'and, as in uffish thought he stood'
-'o frabjous day! callooh! callay!'

those are lines that i found that made absoloutly no sense to me. there were other lines that didnt make very much sense because i didnt know the meaning of certain words (i.e. came whiffling through the tulgey wood) but could make sense of them through guessing what the words meant (came running through the woods).
