Jabberwocky in the context of "Through the Looking-Glass"

Charles Lutwidge Dodgson (27 January 1832 – 14 January 1898), better known by his pen name Lewis Carroll, was an English author, poet, mathematician, photographer and reluctant Anglican deacon. His most notable works are Alice's Adventures in Wonderland (1865) and its sequel Through the Looking-Glass (1871), some of the most important examples of Victorian literature. He was noted for his facility with word play, logic, and fantasy. His poems Jabberwocky (1871) and The Hunting of the Snark (1876) are classified in the genre of literary nonsense. Some of Alice's nonsensical wonderland logic reflects his published work on mathematical logic.

Carroll came from a family of high-church Anglicans, and pursued his clerical training at Christ Church, Oxford, where he lived for most of his life as a scholar, teacher and (necessarily for his academic fellowship at the time) Anglican deacon. Alice Liddell – a daughter of Henry Liddell, the Dean of Christ Church – is widely identified as the original inspiration for Alice in Wonderland, though Carroll always denied this.

Literary nonsense (or nonsense literature) is a broad categorization of literature that balances elements that make sense with some that do not, with the effect of subverting language conventions or logical reasoning. Even though the most well-known form of literary nonsense is nonsense verse, the genre is present in many forms of literature.

The effect of nonsense is often caused by an excess of meaning, rather than a lack of it. Its humor is derived from its nonsensical nature, rather than wit or the "joke" of a punch line.

The Hunting of the Snark, subtitled An Agony, in Eight Fits, is a poem by the English writer Lewis Carroll. It is typically categorised as a nonsense poem. Written between 1874 and 1876, it borrows the setting, some creatures, and eight portmanteau words from Carroll's earlier poem "Jabberwocky" in his children's novel Through the Looking-Glass (1871).

Macmillan published The Hunting of the Snark in the United Kingdom at the end of March 1876, with nine illustrations by Henry Holiday. It had mixed reviews from reviewers, who found it strange. The first printing of the poem consisted of 10,000 copies. There were two reprints by the conclusion of the year; in total, the poem was reprinted 17 times between 1876 and 1908. The poem also has been adapted for musicals, movies, opera, plays, and music.

Nonsense verse is a form of nonsense literature usually employing strong prosodic elements like rhythm and rhyme. It is often whimsical and humorous in tone and employs some of the techniques of nonsense literature.

Limericks are probably the best known form of nonsense verse, although they tend nowadays to be used for straightforward humour, rather than having a nonsensical effect.

A pseudoword is a unit of speech or text that appears to be an actual word in a certain language, while in fact it has no meaning. It is a specific type of nonce word, or even more narrowly a nonsense word, composed of a combination of phonemes which nevertheless conform to the language's phonotactic rules. It is thus a kind of vocable: utterable but meaningless.

Such words lacking a meaning in a certain language or absent in any text corpus or dictionary can be the result of (the interpretation of) a truly random signal, but there will often be an underlying deterministic source, as is the case for examples like jabberwocky and galumph (both coined in a nonsense poem by Lewis Carroll), dord (a ghost word published due to a mistake), ciphers, and typos.
