All of the Sumi languages are basically ergative-absolutive languages, what is odd in the Kurur Sumi language, however is the use of a Dative case, as this is the only known Sumi language to employ this type of case. The Dative case is used in Kurur Sumi to indicate movement to, away , or at an object, making nouns using this case fairly vague as to what its manner of movement is. It is possible that Sampa Sumi once used this case because the allative, elative, inessive, and ablative cases are strikingly similar.
