Unpublished raw data.</ref> Related languages A research list called the "Swadesh 100-word List" presented by Shimizu (1975:414) shows that Tyap (Katab) shares the following cognate percentages with fellow Plateau languages and Jukun beginning from the highest to the lowest: 72% with Izere (Izarek), 66% with Rigwe, 50% with Chara, 49% with Berom, 42% with Tarok, 41% with Pyem, 41% with Ninzam, 39% with Kuche, 39% with Eggon, 38% with Ibunu, 37% with Rindre and 34% with Jukun. Endangered status Research has shown that the Tyap language is classified as one of the endangered languages vulnerable towards extinction. A study by Ayuba (2014) showed that Tyap is endangered and that Hausa language and the non-transmission of Tyap by the older generation of Atyap to the younger generation largely accounted for the endangerment of Tyap. The study recommended, among other measures, that the Atyap Community Development Association (ACDA) should set up a committee to create awareness on the need for Atyap to rise up and save their language and another to work towards establishing vacation schools where older adults would provide pre-school child care where Tyap children could be immersed in the language.
