inessiivis

In Finnish grammar, inessiivis, or the inessive, is a locative case used to indicate a location inside something. It expresses the English “in” or “inside” and denotes a static position rather than movement. It is one of the locative cases in Finnish, alongside elative (from inside), adessive (on/at), allative (onto/to), ablative (off of), and illative (into).

Formation and pronunciation: The inessive suffix is -ssa or -ssä, attached to the noun stem. The choice between -ssa and -ssä follows vowel harmony: the suffix vowel harmonizes with the stem’s last vowels. The common result is a form with -ss- plus the appropriate vowel. Examples include talo → talossa (in the house), vesi → vedessä (in the water), ovi → ovessa (in the door), kivi → kivessä (in the stone).

Usage: The inessive marks locations where something or someone is located. It is used with nouns to express being inside a place or object. For instance, lintu pesässä means “the bird is in the nest.” The form is typically used in descriptive statements about current position, not movement into a place.

Relation to other cases: The inessive contrasts with the illative, which marks movement into something (into the house), and with elative, indicating exit or origin from inside (out of the house). Together with other locative cases, the inessive helps express precise spatial relationships in Finnish grammar.
