Edomite was a Canaanite language, very similar to Hebrew, spoken by the Edomites in southwestern Jordan and parts of Israel in the 1st millennium BCE. It is known only from a very small corpus. Like Moabite, but unlike Hebrew, it retained the feminine ending -t in the singular absolute state. In early times, it seems to have been written with a Phoenician alphabet. However, in the 6th century BCE, it adopted the Aramaic alphabet. Meanwhile, Aramaic or Arabic features such as whb ("gave") and tgr ("merchant") entered the language, with whb becoming especially common in proper names.
According to Glottolog, referencing Huehnergard & Rubin (2011), Edomite was not a distinct language from Hebrew but a Hebraic dialect.
