samanaikaisella

Samanaikaisella is the adessive singular form of the Finnish adjective samanaikainen, which means simultaneous, concurrent, or occurring at the same time. The word is used to describe a noun that is in a time-related relation to another event or situation.

In Finnish grammar, samanaikaisella functions as an agreement form of the adjective, agreeing with the noun in number and grammatical case. Specifically, samanaikaisella occurs when the noun it modifies is in the adessive case (often rendered in English as “on,” “at,” or “with” a temporal context). The corresponding plural form is samanaikaisilla, used with plural nouns in the adessive. The base form samanaikainen can be inflected for other cases and numbers as needed, for example samanaikainen (nominative singular) or samanaikaisiin (illative plural), depending on the sentence.

Common usage centers on signaling simultaneity or concurrency. It is frequently employed in academic, journalistic, and technical Finnish to describe events, processes, or phenomena that occur together in time or overlap.

Examples:

- Samanaikaisella hetkellä sekä tilaisuus että suoritus olivat puitteiltaan epäselviä. (At the same moment, both the event and the performance were unclear in scope.)

- Tutkijat tarkastelevat kahden samanaikaisen ilmiön vaikutuksia. (Researchers examine the effects of two simultaneous phenomena.)

- Hän katsoi samanaikaisella aikavälillä toistuvia tietoja. (He looked at recurring data within the same time period.)

Related terms include samanaikaisuus (the noun form, meaning simultaneity) and synonyms such as yhtäaikainen.
