täsmällisten

Täsmällisten is a Finnish inflected form of the adjective täsmällinen, which means precise, exact, or punctual. It is the genitive plural form and is used before a noun that is in genitive plural to express possession or association with a group described as precise. In practice, this form appears in phrases such as täsmällisten aikataulujen noudattaminen (the adherence to the precise schedules), täsmällisten ohjeiden mukaan toimiminen (acting according to the precise instructions), or täsmällisten mittausten tulokset (the results of the precise measurements).

In Finnish, adjectives agree with the nouns they modify in number and case. When the noun is genitive plural, the adjective takes the genitive plural ending, here -isten. Other forms of the same adjective include täsmälliset in nominative plural and täsmällisiä in partitive plural. The root täsmä- derives from a sense of matching or fitting, and the suffix -llinen turns the root into an adjective meaning “having the quality of.” The form täsmällisten therefore functions strictly as a grammatical case form and is not used as a standalone noun.

Usage notes: täsmällisten is typically found in written or formal Finnish and in contexts describing groups or sets of things regarded as precise or exact. It is most commonly seen in noun phrases where the head noun is in genitive plural, aligning with the structure of Finnish adjective agreement.
