tarkentuu

Tarkentuu is a Finnish verb meaning "to become more precise" or "to be specified/clarified." It describes a process in which details, explanations, or requirements are elaborated over time, often as information becomes available or discussion progresses. The term is used in written and spoken Finnish across technical, journalistic, and administrative contexts to indicate refinement of a plan, instruction, or description.

The verb tarkentua is formed from tarkka (precise) with the verbal suffix -tua, and it is an intransitive verb. In the present tense, tarkentuu is used for third-person singular, with forms such as tarkentuvat in the plural. The past tense is tarkentui. Because it denotes a change of state rather than a transitive action, tarkentuu typically agrees with the subject rather than an object.

Usage examples illustrate its sense of refinement as information becomes clearer. For example: Keskustelu tarkentuu, kun lisätietoja saadaan (The discussion becomes more precise as additional information is obtained). Suunnitelma tarkentuu projektin edetessä (The plan becomes more precise as the project progresses). Ohjeet tarkentuvat, kun vaatimukset ovat selvillä (The instructions are clarified when the requirements are clear).

Related forms include tarkentuminen (the process of becoming more precise) and tarkentunut (refined or clarified in a completed sense). The term is commonly found in reports, updates, and explanatory texts where precision and detail are progressively added.
