A Jabberwocky sentence is a type of sentence of interest in neurolinguistics. Jabberwocky sentences take their name from the language of Lewis Carroll's well-known poem "Jabberwocky". In the poem, Carroll uses correct English grammar and syntax, but many of the words are made up and merely suggest meaning. A Jabberwocky sentence is therefore a sentence which uses correct grammar and syntax but contains nonsense words, rendering it semantically meaningless.
