vaihdettavista

Vaihdettavista is a Finnish grammatical form used in reference to things that can be replaced or exchanged. It is the elative plural form of the adjective vaihdettava, meaning replaceable or exchangeable. In practice, vaihdettavista describes plural nouns in the elative case, often appearing in technical, maintenance, or procurement texts to indicate components or parts that are designed to be swapped.

Grammatically, vaihdettavista consists of the stem vaihdettav-, the adjective ending -a-, and the elative plural ending -sta/-stä, yielding -ista. It typically accompanies a noun in the elative plural, for example vaihdettavista osista, meaning from the replaceable parts. The form contrasts with other cases and numbers, such as vaihdettavat (nominative plural) or vaihdettavissa (in a different mood/context).

Etymology and usage notes: the base is vaihdettava (to be exchanged/replaceable), formed with the causative-like suffix -ttava to create an adjective, and then inflected for case and number as needed. Vaihdettavista is common in technical manuals, spare-parts catalogs, and service documentation when specifying which components are designed to be replaced. It is part of a broader family of Finnish adjective forms that describe replaceability or interchangeability.
