Aikavälille

Aikavälille is a Finnish grammatical form used to indicate the scope or domain of something that is bounded by a time interval. It is formed from the noun pair aika (time) and väli (interval) with the allative suffix -lle, meaning “to the time interval” or “for the time window.”

Usage and meaning

Aikavälille is commonly used in statistics, research reports, planning documents, and data descriptions to specify that a statement, data set, or effect applies to a particular time window. It emphasizes the temporal boundary of the subject rather than a specific moment. The form is closely related to aikaväli (time interval) and its other case forms, such as aikavälillä (within the time interval) and aikaväleille (to the time intervals).

Related terms
