ylläpitämillä

Ylläpitämillä is a Finnish grammatical form derived from the verb ylläpitää, meaning to maintain. It functions as a past passive participle in plural adessive or instrumental use, typically appearing with plural nouns to describe things that are maintained or kept in a maintained state. The form is not a standalone lexical item but an inflected participial form used in descriptive and technical prose, especially in contexts such as infrastructure, services, or organizational governance.

Formation: The participle stem is usually analyzed as ylläpitämä, meaning “maintained.” The plural adessive/instrumental suffix -illä attaches to create ylläpitämillä, which is used with a plural noun. In sentences, ylläpitämillä can modify the noun in its plural form to express “with the maintained [plural noun]” or “the ones that are maintained by.”

Usage: The form is common in administrative, technical, and project documentation, where it helps describe conditions of objects that are being maintained by someone or something. It often appears in phrases such as ylläpitämillä järjestelmillä (with the maintained systems) or ylläpitämillä resursseilla (with the maintained resources).
