Primitive Adûnaic is the form of the Adûnaic language spoken when the Men of the West first colonized Númenor. Since Adûnaic developed from the Hadorian language of the Edain (S/147-8, PE17/18), it is possible that Primitive Adûnaic was similar or identical to that language as it was spoken at the end of the First Age. Tolkien did not describe much of the language and vocabulary of the old form of this language. Most of his descriptions focused on the phonetic development of the language into the Classical Adûnaic form spoken at the end of the Second Age.
