 Its corpus, already a varied mixture of Khuzdul, Avarin, and Sindarin, was probably now exposed more heavily to the influence of Quenya (which served a role much the same as Latin in Medieval Europe) and possibly even Valarin, both due to regular contact with Aman.When the Númenóreans began to establish trading ports (later colonies) on the western shores of Middle-earth, Adûnaic mingled with the languages of various groups of Edain who had not travelled to Númenor, and the resulting trade language quickly spread throughout Eriador and its neighbours, laying the foundation for the later Common Speech.Following the Akallabêth, the surviving Elendili who established the kingdoms of Arnor and Gondor shunned Adûnaic in favour of Sindarin due to the associations of the former with the tyrannical Ar-Pharazôn and his followers the King's Men.
