ylläpidettyyn

Ylläpidettyyn is a Finnish grammatical form derived from the verb ylläpitää, meaning to maintain or keep up. It is the illative case form of the past passive participle ylläpidetty, which translates roughly as "maintained" or "kept." As an illative form, ylläpidettyyn is used to indicate direction toward something that has been maintained.

Morphologically, ylläpidettyyn combines the past passive participle stem ylläpidetty with the illative case suffix. In Finnish, illative forms convey movement into or toward a place, state, or condition, and ylläpidettyyn is commonly used with nouns that are in illative case. The form appears in technical, IT, and maintenance-related language, where it describes a destination or target that has undergone maintenance or preservation.

Usage and context are typically technical or formal. Ylläpidettyyn is often found in phrases describing systems, environments, or versions that have been kept up-to-date or kept in a maintained state. For example, it can appear in sentences like “järjestelmä on siirretty ylläpidettyyn ympäristöön,” meaning “the system has been moved to a maintained environment,” or “päivitykset asennetaan ylläpidettyyn ohjelmistoversioon,” meaning “updates are installed into the maintained software version.”
