täsmällistävät

Täsmällistävät is a Finnish verb form meaning “they specify” or “they make precise.” It is the present tense, third-person plural form of the verb täsmällistää, used when the subject is plural.

Form and etymology. The verb täsmällistää is built from the adjective täsmällinen (precise) with the causative suffix -istää, creating a transitive verb meaning “to make something precise” or “to specify.” In the present indicative, the third-person plural ending is -vät, yielding täsmällistävät. The construction is characteristic of formal or technical Finnish and is more common in written texts than in everyday speech.

Usage. Täsmällistävät occurs mainly in formal or technical contexts—such as contracts, regulations, manuals, and academic writing—where it is important to specify details exactly. It describes actions carried out by multiple agents who specify terms or clarify details. Examples:

- Yhtiö ja asiakkaat täsmällistävät sopimuksen ehtoja.

- Käyttöohjeet täsmällistävät prosessin vaiheita.
