Sisätilojensa

Sisätilojensa is a Finnish possessive construction used to indicate ownership of interior spaces. Grammatically, it is formed from the plural genitive stem of the noun sisätila (interior space) — sisätilojen — followed by the third-person possessive suffix -nsa or -nsä, resulting in sisätilojensa. The exact form of the suffix (nsa vs. nsä) follows vowel harmony rules and is chosen to agree with the preceding vowels.

Formation and meaning

- Base: sisätila (interior space)

- Plural genitive: sisätilojen (of the interior spaces)

- Possessive suffix: -nsa / -nsä (his/her/its or their)

- Result: sisätilojensa, meaning “of its interior spaces” or “of their interior spaces,” depending on the possessor in the broader sentence.

Usage

Sisätilojensa is typically used in formal or descriptive contexts, especially in architecture, interior design, real estate, and planning discourse. It often appears with a noun in genitive singular preceding it (the possessor) to specify whose interior spaces are being discussed. Examples:
