Fictional languages vary: among J. R. R. Tolkien's languages for the Middle-earth universe, for example, Sindarin is fusional while Quenya is agglutinative. The language Newspeak from 1984 is a variant of English derived from the very concept of agglutination. Among engineered languages, Toki Pona is completely analytic, as it contains only a limited set of words with no inflections or compounds. Lojban is analytic to the extent that every gismu (basic word, not counting particles) involves pre-determined syntactical roles for every gismu coming after it in a clause, though it does involve agglutination of roots when forming calques. Ithkuil, on the other hand, contains both agglutination in its addition of affixes and extreme fusion in that these affixes often result from the fusion of numerous morphemes via ablaut.
