käyttöönottamassaan

käyttöönottamassaan is a Finnish word derived from the verb "käyttöön ottaa," meaning "to put into use," "to launch," or "to implement." The "-ssa" ending signifies the inessive case, indicating "in" or "within." The "-an" ending denotes the possessive suffix, meaning "in what he/she/it/they have put into use." Therefore, käyttöönottamassaan translates to "in what he/she/it/they have put into use" or "in its implementation."

This grammatical form is often used to refer to a system, device, process, or project that has been introduced and is currently being operated or utilized. For example, one might say "järjestelmän käyttöönottamassaan" meaning "in the system that has been put into use." It implies a state of being operational after an initial introduction or launch phase. The context in which it appears would clarify precisely what has been implemented and is now in operation. It is a compound word that highlights both the action of implementation and the state of being in use.
