ostoissa

Ostoissa is a Finnish grammatical form meaning “in the purchases” or “in the act of purchasing.” It is the inessive plural form of the noun osto, which denotes a purchase, acquisition, or procurement. The form is used mainly in written language, particularly in statistical, economic, or business contexts, to refer to multiple purchases or to the state of purchasing activities.

In usage, ostoissa appears when describing phenomena connected to purchases on a collective level rather than a single transaction. It can be used in sentences such as “Tilastojen mukaan ostoissa on ollut vaihtelua viime vuosina,” meaning that there has been variation in purchases according to the statistics, or “Ostoissa tapahtuneet viiveet vaikuttavat toimitusaikoihin,” referring to delays in purchases affecting lead times. In everyday Finnish, speakers more often use ostot (purchases) or refer to buying activity with phrases rather than the inessive plural form.

Related forms include osto (singular), ostot (plural nominative), ostoa (partitive), and ostamisen (gerund). The term is part of the broader vocabulary of commerce and procurement in Finnish and is commonly encountered in reports, market analyses, and government or corporate disclosures.
