The pertingent case is a grammatical case found in the Tlingit language.[1] It is used to refer to something which is touching something else: for example, in English, "the chair touching the table", or "against the wall".
In the Tlingit language, the pertingent case is marked with the suffix Tlingit: -x̱. For instance, Tlingit: ÿax̱- is the pertingent form of Tlingit: ÿán, meaning “shore”. In Tinglit, the case may also be used to refer to the membership of a group. The phrase Tlingit: Kaagwaantaan-x̱ means “they are of the Kaagwaantaan clan”. This usage of the case can be found in sentences containing stative imperfectives that refer to multiple positions. For example, the phrase Tlingit: áx̱ naadákwt means “bodies of water lie here and there upon it.”[2]
It is also found in the Archi language.
