läpikuultamattoman

läpikuultamattoman is the genitive singular form of the Finnish adjective läpikuultamaton. This adjective translates to "opaque" in English. An opaque object or material is one that does not allow light to pass through it. In contrast, transparent materials allow light to pass through so clearly that objects on the other side can be seen, while translucent materials allow light to pass through but scatter it, making objects on the other side appear blurry. Therefore, läpikuultamattoman describes something that possesses the quality of being opaque.

The genitive case in Finnish, indicated by the ending "-n" in this instance, typically expresses possession, origin, or a relationship between two nouns. Thus, läpikuultamattoman would be used in a sentence to describe the opacity of something belonging to or related to another entity. For example, one might refer to the läpikuultamattoman pinnan (the opaque surface's) texture or the läpikuultamattoman materiaalin (the opaque material's) properties. The term is purely descriptive of a physical characteristic.
