käytetystä

Käytetystä is the elative singular form of the Finnish adjective and past participle käytetty, meaning "used" or "second-hand." Käytetty functions as both an adjective and a participle derived from the verb käyttää (to use). The elative case, marked by the suffix -stä/-stä, expresses origin or source, so käytetystä is used to indicate something that comes from something that has already been used.

In practice, käytetystä appears in phrases describing objects or materials that originate from a used item. Examples include käytetystä autosta (from a used car) and käytetystä tavarasta (from used goods). The form agrees with the noun in number and case, and is part of a broader pattern where other cases of the same adjective take forms such as käytetyn (genitive), käytettyä (partitive), käytetyssä (inessive), and käytettyyn (illative).

The term is common in everyday Finnish, particularly in contexts involving second-hand markets, recycling, refurbishment, or descriptions of items that are not new. It helps distinguish the condition or provenance of an object without altering the noun itself.

Relation to related forms: käytetty as the basic form describing something that has been used; käytettyjä tuotteita would refer to "used products" in plural; käytetyn tavaran indicates possession in genitive. The word derives from käyttötarkoituksesta to emphasize the status of an item as previously utilized.
