Arkkitehtuurillisissa

Arkkitehtuurillisissa is the inessive plural form of the Finnish adjective arkkitehtuurillinen, meaning architectural. It is used with a plural noun in the inessive case to express “in architectural terms” or “in terms of architectural features.” The form cannot stand alone; it modifies a noun such as piirissä, ympäristöissä, or ominaisuuksissa.

Etymology and grammar: arkkitehtuurillinen is derived from arkkitehtuuri (architecture) plus the suffix -llinen, which yields an adjective meaning “pertaining to architecture.” When the modified noun is plural and in the inessive case, the adjective takes the form arkkitehtuurillisissa. This pattern illustrates Finnish adjective inflection and the use of case with descriptive modifiers.

Usage and context: The form is common in Finnish architectural criticism, design history, and academic writing where descriptions refer to multiple architectural aspects. Examples include: “Rakennuksen arkkitehtuurillisissa piirteissä korostuvat funktionalistiset linjat,” meaning that the architectural features emphasize the functionalist lines; and “Kaupungin arkkitehtuurillisissa ympäristöissä voidaan nähdä aikakausien kerrostumia,” indicating layers of eras in the architectural surroundings.

Related forms: The adverbial counterpart is arkkitehtuurillisesti, used to describe how something is done in an architectural manner. The base adjective arkkitehtuurillinen can also appear in singular forms to modify a single noun (arhitehtuurillinen piirre, arkkitehtuurillinen rakennus), while arkkitehtuurillisissa is specifically aligned with plural inessive constructions.

In summary, arkkitehtuurillisissa is a specialized Finnish grammatical form employed to discuss architecture-related features in a plural, inessive context, typical in professional and scholarly texts.
