Lisätiivi

Lisätiivi, also known as an adessive case, is a grammatical case used in some languages, particularly in the Finno-Ugric language family, to indicate the location of an object or person in relation to a surface or area. It is often used to describe a situation where something is on or near a surface, such as "on the table" or "near the wall."

In Finnish, for example, the adessive case is formed by adding the suffix "-lla" or "-llä" to the noun. The choice between "lla" and "llä" depends on the vowel harmony rules of the Finnish language. For instance, "pöydällä" means "on the table" and "seinällä" means "on the wall."

The adessive case is distinct from other locative cases like the inessive, which indicates a location inside an object, and the elative, which indicates movement away from a location. The adessive case is also different from the allative, which indicates movement towards a location.

The use of the adessive case can vary between languages. In some languages, it may be used more frequently, while in others, it may be less common. However, it is a valuable tool for expressing precise spatial relationships in language.
