Ammattimaisilla

Ammattimaisilla is the plural adessive form of the Finnish adjective ammattimainen, meaning professional, professional‑grade, or of a professional standard. It is used to describe nouns in the adessive case, typically to indicate that something has professional characteristics, adheres to professional standards, or is performed in a professional manner. In Finnish, adjectives agree with the nouns they modify in number and case, so ammattimaisilla is the form used when the noun is plural and in the adessive case.

The word is formed from the stem ammattimainen (derived from ammatti, profession) with the common -inen adjective ending, and then inflected to the adessive plural -illa. Thus ammattimaisilla appears before a plural noun in the adessive, for example ammattimaisilla standardeilla or ammattimaisilla taidoilla, to express “with professional standards” or “with professional skills.”

Usage notes: Ammattimaisilla is most common in formal, technical, or marketing language to signal quality or compliance with professional norms. It often emphasizes external attributes such as standards, practices, or behavior associated with a profession, rather than identifying the people themselves. While related terms include ammattimainen (professional in general) and ammatti (profession), ammattimaisilla specifically marks the adessive plural form of the adjective.
