Taliska
From Tolkien Gateway
Taliska was the language spoken by the Bëorian (First) and Hadorian (Third) Houses of the Atanatári, who spoke different dialects.
The Second House of Men spoke an unrelated language, the Haladin tongue. This language and Taliska were not mutually intelligible.
The exact origin of Taliska is not clear, but certain is that there are both Elvish and Dwarvish (Khuzdul) influences, suggesting the Atanatári (Fathers of Men) had contacts with both peoples before arriving in Beleriand.
