metallisissa

Metallisissa is a Finnish term that denotes the inessive plural form of the noun metalli, meaning “in the metals” or “within metal materials.” In Finnish grammar, the inessive expresses location inside something, and the plural form is used when referring to multiple metals or metal-containing contexts. The word is most typical in technical and scientific texts dealing with metallic systems, alloys, or metal-related phenomena.

Etymology and form: Metallisissa is formed from the base metalli with the inessive plural suffix, indicating a location within metals or metal environments. While everyday Finnish often uses metallissa (singular) or metalleissa (plural) in similar contexts, metallisissa reflects the plural subject or scope.

Usage: The term appears primarily in metallurgy, materials science, corrosion studies, and related fields where discussions concern processes, properties, or conditions inside metals or across different metals and metal alloys. Its use signals a focus on phenomena that are intrinsic to metallic systems rather than to pure substances or external environments.
