palautettavan
Palautettavan is a Finnish grammatical form derived from the participial adjective palautettava, meaning "returnable" or "to be returned." The word itself is the genitive singular form of that adjective and is used to modify a noun in contexts where the noun is in a case such as genitive or when the phrase is part of a larger noun compound.

Morphologically, palautettavan follows the pattern of Finnish adjectives, declining to agree with the noun it modifies.
Etymology: the word combines the verb palauttaa (to return) with the participial suffix -ttava, yielding an adjective
Palautettavan is thus a specialized adjective form used to specify items or documents associated with return
