Tarvitun

Tarvitun is a Finnish inflected word, the genitive (and accusative) singular form of the past participle tarvittu, derived from the verb tarvita meaning "to need" or "to require." As a participial adjective, tarvittu describes something that is needed or required; tarvittun is used when the participle appears in grammatical contexts that call for the genitive/accusative case, for example in noun phrases and nominalizations.

Usage examples include expressions like "tarvitun avun saaminen kesti kauan" ("obtaining the needed help took a long time") and "hän otti tarvitun määrän materiaalia" ("he took the required amount of material"). Tarvitun appears in written and spoken Finnish wherever the nuance "of the needed" or "required" must be marked by case agreement with surrounding words.

Morphologically, tarvittu is formed from the stem of tarvita and shows regular participle inflection; tarvitun follows standard Finnish case endings. Cognates and related verbs occur in other Finnic languages (for example Estonian verbs with similar roots), reflecting a common Finnic heritage. The form tarvitun is neutral in register and common in formal, administrative, and everyday contexts where precise specification of requirements or quantities is needed.
