ostettuun

The word "ostettuun" is the illative plural form of the Finnish word "ostettu". "Ostettu" itself is the past passive participle of the verb "ostaa", which means "to buy". Therefore, "ostettuun" translates to "into the bought ones" or "into those that were bought". This grammatical form is used to indicate movement into or a change of state concerning multiple items that have been purchased. For example, one might say "Lapsi laittoi ostettuun leluun pariston" which translates to "The child put a battery into the bought toy" (using the singular illative form "ostettuun"). In its plural illative form, it would be used in a context such as "Lapsi laittoi ostettuihin leluihin paristoja" meaning "The child put batteries into the bought toys". The illative case in Finnish expresses movement into a location or into a state. Its usage with the past passive participle signifies becoming part of or entering into a condition that is the result of being bought.
