"Jabberwocky" is a nonsense poem written by Lewis Carroll about the killing of a creature named "the Jabberwock". It was included in his 1871 novel Through the Looking-Glass, the sequel to Alice's Adventures in Wonderland (1865). The book tells of Alice's adventures within the back-to-front world of the Looking-Glass world.

In an early scene in which she first encounters the chess piece characters White Kingand White Queen, Alice finds a book written in a seemingly unintelligible language. Realising that she is travelling through an inverted world, she recognises that the verses on the pages are written in mirror writing. She holds a mirror to one of the poems and reads the reflected verse of "Jabberwocky". She finds the nonsense verse as puzzling as the odd land she has passed into, later revealed as a dreamscape.[1]

"Jabberwocky" is considered one of the greatest nonsense poems written in English.[2][3]

When Alice has finished reading the poem she gives her impressions:

"It seems very pretty," she said when she had finished it, "but it's rather hard to understand!" (You see she didn't like to confess, even to herself, that she couldn't make it out at all.) "Somehow it seems to fill my head with ideas—only I don't exactly know what they are! However, somebody killed something: that's clear, at any rate."[1]

This may reflect Carroll's intention for his readership; the poem is, after all, part of a dream. In later writings he discussed some of his lexicon, commenting that he did not know the specific meanings or sources of some of the words; the linguistic ambiguity and uncertainty throughout both the book and the poem may largely be the point.[17]
