Lewis Carroll's "Jabberwocky" is a nonsense poem filled with words that have no actual meaning. As such, the poem is not necessarily about anything in particular. Instead, the difficulty the reader has in putting meaning to its words is a part of the poem itself.
"Jabberwocky" appears in Lewis Carroll's "Through the Looking-Glass, and What Alice Found There," a sequel to "Alice's Adventures in Wonderland." Many of the nonsensical words Carroll used in the poem later entered common English usage, such as the term "chortle," a combination of a chuckle and a snort.
Carroll himself stated that he did not know the meaning of some of the words, indicating that the ambiguous meaning was intentional and not a puzzle with a correct interpretation.
