ministeriöissä

Ministeriöissä is the Finnish inessive plural form of the noun ministeriö, meaning "in the ministries" or "inside the ministries." As a grammatical form, it uses the inessive plural case marker -issa/-issä (here -issä because of vowel harmony), which indicates location within multiple entities. The word combines the base ministeriö (a government ministry or administrative department) with the plural locative ending to express action or state occurring inside several ministries.

In usage, ministeriöissä appears in contexts discussing policies, meetings, procedures or conditions that take place across more than one ministry. For example: "Muutokset valmistellaan ministeriöissä" — "Changes are prepared in the ministries." It commonly occurs in news reporting, academic writing and official documents when referring to inter-ministerial coordination or comparative practices between ministries.

The term is neutral and formal, reflecting administrative language. Related forms include ministeriössä (singular inessive, "in the ministry"), ministeriöt (nominative plural, "ministries") and ministeriöiden (genitive plural, "of the ministries"). Understanding ministeriöissä helps with reading Finnish texts about government operations, public administration and legislative processes.
