samanaikaiseen

Samanaikaiseen is a Finnish inflected form of the adjective samanaikainen, meaning concurrent or simultaneous. It is the illative singular form, used when the modified noun is in illative case, often translating to “to a concurrent/simultaneous [use, state, event].” A common illustration is samanaikaiseen käyttöön, meaning “for concurrent use.” The form reflects how Finnish adjectives agree with nouns for case and number.

Samanaikainen describes things that happen at the same time or overlap in time. In practical language, samanaikaiseen appears in formal and technical contexts to specify that several actions, processes, or conditions are intended to occur together rather than sequentially. It is commonly found in medical, pharmacological, and research or technical writing.

Usage examples include a sentence such as Lääkkeet voidaan ottaa samanaikaiseen käyttöön, which indicates that medicines may be used concurrently. Another example is Kaksi tapahtumaa tapahtuivat samanaikaisesti, using the base meaning to describe events occurring at the same time. In everyday Finnish, speakers may also use adverbs like samanaikaisesti to express simultaneity, while samanaikaiseen remains typical in written or specialized prose.
