Teonaht /ˈteɪ.oʊnæθ/ is a constructed language that has been developed since 1962 by science fiction writer and University of Rochester English professor Sarah Higley, under the pseudonym of Sally Caves. It is spoken in the fantasy setting of the Teonim, a race of polydactyl humans who have a cultural history of worshiping catlike deities. Teonaht is often cited as an example of the genre in articles on the world of Internet-hosted amateur conlanging.
