Adunaik

When the Edain awoke in Middleearth at the first sunrise, they almost immediately started inventing their language. However, their creative efforts were first in vain – Talisca turned out to be a mixture of Nandorin and Khuzdul. In Beleriand, Men were eager to study Sindarin – and quickly turned it into the predominant language of the realms of Men. When Numenor was founded, Adunaik developed as a grammatically, phonetically and structurally complete language.

The language was a lavish mixture of Talisca with Elvish tongues, primarily Sindarin. Numenorean rulers, starting with the sixteenth king, had two names, one, according to the tradition, was in Quenya, the other one in Adunaik. Very soon after the downfall of Numenor, Adunaik was abandoned, as the kin of Isildur and Earendil returned to using Sindarin. However, it was Adunaik that gave rise to the primary language of the Third and Fourth Ages – Westron, the Common Speech.
