keskustellun

Keskustellun is a Finnish grammatical form that appears in attributive phrases to indicate that the noun it modifies refers to something that has already been discussed. It is the genitive singular form of the past active participle keskustellut, used as an adjective before a noun.

In practice, keskustellun is most commonly seen in phrases such as keskustellun aiheen käsittely or keskustellun aiheen tiivistelmä. These mean “the handling of the discussed topic” and “a summary of the discussed topic,” respectively. The construction allows speakers and writers to specify that the topic has already been the subject of discussion, providing a precise temporal status for the noun.

Keskustellun is distinct from the genitive of the noun keskustelu. The genitive of that noun is keskustelun (for example, keskustelun aiheen would be “the topic of the discussion”). By contrast, keskustellun aiheen uses the participial adjective form to convey that the topic itself has been discussed, rather than simply belonging to a discussion.

Usage notes:

- Keskustellun is primarily found in written Finnish, including academic, administrative, and formal journalistic styles, where exact relationships between topics and discussions are important.

- The form can sometimes be initially confusing for learners, because it blends verb-derived participle meaning with noun modification. Context usually clarifies whether the intention is “the discussed topic” (keskustellun aiheen) or something more directly related to a discussion of a topic (keskustelun aiheen).

Overall, keskustellun functions as a precise, participle-based modifier used to tag nouns with the sense that they have already undergone discussion.
