kustannustensa

Kustannustensa is a Finnish possessive form derived from kustannus, meaning cost or expense. It marks the costs that belong to a subject, typically a third party such as a company, government body, or household. In practice, kustannustensa is used to express “their costs” or “the costs of them,” depending on the sentence and context. It often appears in formal or professional writing, especially in budgeting, policy analysis, and financial reporting.

Usage examples in context illustrate its function as a possessive construction within noun phrases. Phrases such as kustannustensa hallinta (the management or control of their costs), kustannustensa leikkaaminen (the reduction of their costs), or kustannustensa kattaminen (the covering or funding of their costs) show how the form integrates with common economic concepts. The exact meaning is determined by the surrounding clause and the actor whose costs are being discussed.

Grammar note: Finnish possessive forms attach to the possessed noun and reflect the possessor through suffixal morphology. The form kustannustensa relies on the third-person possessive suffix and interacts with vowel harmony and number; variations can occur depending on the grammatical construction and dialect. It is not a separate semantic concept, but a grammatical way to refer to costs owned by someone or something.

Related terms include kustannus (cost), kustannukset (costs), kustannuslaskenta (cost accounting), and kustannusylitys (cost overrun). Kustannustensa is primarily a functional form used in economic, legal, and administrative Finnish to describe expenses attributed to a subject.
