ammattilaisesta

Ammattilaisesta is the elative singular form of the Finnish noun ammattilainen, meaning a professional or expert. The elative case suffix -sta/-stä expresses origin, source, or the topic of discussion. Accordingly, ammattilaisesta can translate as "from a professional" or "about a professional," depending on context.

Ammattilainen means a professional or an expert, a person who is employed professionally in a field or who has high level expertise. The term is built from ammatti (profession) and the suffix -lainen, which denotes a person associated with or characterized by something. The word is closely related to discussions of expertise, qualifications, and professional standards.

In use, ammattilaisesta appears in sentences where the elative sense is required. For example: "Puhumme ammattilaisesta" (We are talking about a professional) and "Tiedot ammattilaisesta tulivat viranomaisilta" (The information from/about a professional came from authorities). The form contrasts with ammattilaisen (genitive singular) and ammattilaisista (elative plural).

Declension: Singular elative is ammattilaisesta; plural elative is ammattilaisista.

Some notes: The elative can express both origin and topic, and is common in journalism, academic writing, and formal Finnish when referring to professionals and expert sources. See also ammattilainen for the base form, and ammattilaisuus or ammattilaisuudesta for related concepts in professional status and related talks.
