päivittäiseen

Päivittäinen is a Finnish adjective meaning “daily” or “everyday.” It describes something that occurs or is used on a day-to-day basis. The word is formed from the noun päivä (day) and belongs to the common Finnish -inen adjective class, which creates descriptors that express a property or relation to the noun they modify.

Päivittäinen is frequently placed before nouns, for example: päivittäinen käytäntö (a daily practice), päivittäinen ohjelma (a daily schedule), or päivittäinen elämä (daily life). Like other adjectives ending in -inen, päivittäinen is inflected to agree with the noun in number and case. The illative singular form, päivittäiseen, appears in phrases such as päivittäiseen käyttöön (for daily use) or päivittäiseen elämään (into daily life), where the noun it modifies is in the illative case.

Grammatical note: as with Finnish adjectives in the -inen group, päivittäinen takes the appropriate inflection to match the genderless noun it accompanies. The illative form päivittäiseen is used when the noun it modifies is in illative (toward or into a direction or purpose related to daily life or use). This form helps express motion toward or application to daily phenomena or routines.

Usage and nuance: päivittäinen is common in formal, instructional, and written Finnish. In everyday speech, jokapäiväinen is frequently used as a natural synonym, though päivittäinen can convey a slightly more formal or technical tone, depending on context.
