tilallisuudesta

Tilallisuudesta is the Finnish elative singular form of the abstract noun tilallisuus, which denotes spatiality, the quality or condition of being spatial or related to space. Morphologically it is formed from tila (space, room) with adjectival and nominal suffixes (-llinen, -isuus) and the case ending -sta, so tilallisuudesta can be translated as "from spatiality" or "about spatiality" depending on context.

In linguistic and theoretical usage tilallisuus refers to how space is organized, represented and experienced, including spatial relations, orientation, topology and scale. Disciplines such as geography, architecture, urban studies, cultural studies and literary analysis use the concept to examine how physical and conceptual spaces shape behavior, meaning and social relations. For example, discussions of public versus private space, spatial metaphors in language, or narrative settings may be described as keskustelu tilallisuudesta ("a discussion about spatiality").

Grammatically, the ending -sta marks elative case (movement out of or source) and is also used idiomatically to indicate topic when paired with verbs of discussion, criticism or study. Examples: kirjoitus tilallisuudesta ("a writing about spatiality"), tutkimus tilallisuudesta ("research on spatiality"). The term is chiefly used in Finnish academic and critical contexts and is connected etymologically to other spatial vocabulary such as tila, tilasto (from the same root in different compounds), and tilallinen (spatial, positional).
