Tilallisella

Tilallisella is a Finnish linguistic form that functions as the adessive singular of the adjective tilallinen. In Finnish, the adessive case marks location or a related sense with the suffix -lla/-llä, so tilallisella would be used in contexts where the phrase is interpreted as "on/at the tilallinen" or, more broadly, "pertaining to tilallinen" within a sentence.

Etymology and meaning are tied to the root tila, which in various compounds relates to orders or arrangements, and to the adjective tilallinen, a derivation that can describe something related to an order or to a customer in specialized usage. However, tilallinen itself is not common in everyday Finnish, and tilallisella appears mainly in technical, legal, or historical texts where precise inflectional forms are discussed or demonstrated.

Usage and frequency are limited. In contemporary everyday language, speakers typically express similar ideas with clearer phrases such as asiakkaan puolella (on the customer’s side) or tilaajan näkökulmasta (from the orderer’s perspective). Tilallisella may nevertheless occur in linguistic descriptions, grammar exercises, or documents illustrating Finnish inflection patterns, where it serves as an example of how adjectives ending in -inen decline in the adessive.
