Edomite language
Edomite was a Northwest Semitic Canaanite language spoken by the Edomites in Idumea (modern-day southwestern Jordan and parts of Israel) in the 2nd and 1st millennium BC. It is extinct and known only from an extremely small corpus, attested in a scant number of impression seals, ostraca, and a single late 7th or early 6th century BC letter, discovered in Horvat Uza. Like Moabite, but unlike Hebrew, it retained the feminine ending -t in the singular absolute state.
