Short answers, pulled from the story.
Lewis Carroll wrote the first stanza of Jabberwocky in 1855 while staying at Croft-on-Tees. He published it that same year in a family periodical called Mischmasch under the title Stanza of Anglo-Saxon Poetry.
Carroll constructed many words by blending existing terms into single units to create portmanteaus. The word chortle combines chuckle and snort according to the Oxford English Dictionary, while frumious merges fuming and furious into one term.
Translators have adapted Jabberwocky into sixty-five different languages worldwide including French, Russian, Chinese, Brazilian Portuguese, Bengali, Latin, Ancient Greek, and others. Frank L. Warrin translated it into French as Il brilgue to preserve the invented nature, and D.G. Orlovskaya created Barmaglot for the Russian edition published in 1967.
Christopher Lee voiced the creature in Tim Burton's 2010 film adaptation of Alice in Wonderland. John Tenniel agreed to illustrate the book in 1871 for Through the Looking-Glass, and his images became the defining visual representation of the creature known as the Jabberwock.
G.K. Chesterton argued that the original purpose was satire against pretentious verse and ignorant critics. Roger Lancelyn Green suggested it mocked contemporary Oxford scholarship specifically regarding Benjamin Jowett.
