Noun case

Language families

• With a few exceptions, most languages in the Finno-Ugric family make extensive use of cases. Finnish has 15 cases according to the traditional description (or up to 30 depending on the interpretation). However, only 12 are commonly used in speech (see Finnish noun cases and Finnish locative system). Estonian has 14 (see Estonian locative system) and Hungarian has 18, both with additional archaic cases used for some words.
• Turkic, Mongolic, and Tungusic languages also exhibit complex case systems. Since the abovementioned languages, along with Korean and Japanese, shared certain similarities, linguists proposed an Altaic family and reconstructed its case system; although the hypothesis had been largely discredited.
• The Tsez language, a Northeast Caucasian language, has 64 cases.
• The original version of John Quijada's constructed languageIthkuil has 81 noun cases, and its descendant Ilaksh and Ithkuil after the 2011 revision both have 96 noun cases.
