Prepositional case

Prepositional case (abbreviated PREP) is a grammatical case that marks the object of a preposition. This term can be used in languages where nouns have a declensional form that appears exclusively in combination with certain prepositions. For example, in Russian and Polish, the case that appears with (non-directional) uses of the prepositions na, w, przy, o (roughly, "on", "in", "near", "about") is traditionally referred to as the prepositional case (Russian: предложный падеж, predlóžnyj padéž).
