tiettyyn

Tiettyyn is the illative singular form of the Finnish adjective tietty, meaning “certain” or “specific.” It is used to indicate movement toward or into a definite referent, place, time, or purpose, and it often appears in phrases that constrain meaning to a particular instance.

In practice, tiettyyn accompanies a noun in illative cases such as to a certain direction, time, place, or purpose. Examples include tiettyyn suuntaan (in a certain direction), tiettyyn aikaan (at a certain time), tiettyyn paikkaan (to a certain place), and tiettyyn tarkoitukseen (for a specific purpose). The construction emphasizes the definite, restricted nature of what is being talked about.

Usage notes:

- Tiettyyn is most common in formal or careful prose, but it also occurs in everyday speech when precision is important.

- The phrase often functions as a modifier of the following noun, but it can also appear in more complex clauses to mark specificity, such as “haluamme saavuttaa tiettyyn lopputulokseen” (we want to reach a certain outcome).

- The base form tietty is used for general reference, while tiettyyn shows the illative “to a certain/particular” sense in context.

Overall, tiettyyn helps specify definite referents and purposes in Finnish, aligning with the language’s characteristic use of illative forms to express directed or targeted meanings.
