kuviteltuun
Kuviteltuun is a Finnish grammatical form, the illative singular of the adjective kuvitteltu, which means imagined or fictional. It is used to describe something that is directed toward or enters into an imagined entity, such as an imagined world or future. In Finnish, adjectives agree with the nouns they modify in case, so kuvitetluun forms appear before a noun in the illative case.
The base verb is kuvitella, meaning to imagine. The related participle kuvitteltu functions as an adjective
