Origins and family
Adûnaic was derived from the Hadorian tongue, related to the Bëorian—collectively called Taliska. It was more distantly related to the languages of the Middle Men of the east, such as the Men of Eriador and the Northmen. During the First Age these languages were much influenced by Khuzdul, Avarin, but also by the languages of the Eldar, as the Elf-friends spoke Sindarin.
Despite it being a millennium or more after their separation, the Númenórean mariners who returned to Middle-earth in the Second Age could find common roots and words with the Middle Men of Eriador (related to the Folks of Beor and Hador), and talk about simple matters. This is also partly due to the Númenórean longevity, and the slow change of their language.
In the western districts of Númenor, the rustic folk still used another dialect, a last remnant of the Bëorian language.
Adûnaic was generally considered to be a language of less prestige than the Elven tongues. Most locations of Númenor, and most of the lords and ladies of the Dúnedain, had also Quenya or Sindarin names beside their native ones. Even most commoners knew Sindarin to some degree.
Most of the House of Bëor had been killed after the Dagor Bragollach, but even during the Second Age a Bëorian accent of Adûnaic still survived in parts of Númenor, most notably in Emerië and around the harbour of Andúnië.
 Days of pride
About 2,000 years into the Second Age, the Númenóreans began to envy the immortality of the Firstborn, which extended to the languages of the Elves; the Kings and their followers used the Elven tongues less and less. Though the Kings and Queens had all taken their names in Quenya, after some time their supporters used their Adûnaic names to refer to them.
Eventually Ar-Adûnakhôr took his name in Adûnaic and forbade anyone to speak the Elven tongues in his presence. Adûnaic was now the language of the royal court. Its supremacy was most strongly enforced by Ar-Gimilzôr: he outlawed the use of Elvish anywhere in Númenor, which antagonized the few Faithful Númenóreans still living in the land.
However, his son Inziladûn took a Quenya name again, Tar-Palantir, repealed the ban on the Elven tongues and gave peace to the Faithful. His daughter Míriel would probably have continued his reforms, but her cousin Pharazôn seized power and, in addition, gave her an Adûnaic name (Ar-Zimraphel).
In Middle-earth, the Faithful settlers (who controlled the shorelands of the Westlands from Lune to Pelargir), neglected their native tongue and favored Sindarin and devised names in it; no doubt as a reaction against the rebel Kings who banned the Elvish tongues. This was the case among the Faithful of high lineage who used Sindarin as their native tongue, and became a mark of Númenórean descent, while Adûnaic was left as the daily language of the illiterate, neglected to unheeded change. However some Númenóreans who had Sindarin as their mother tongue, learned this "vulgar" language when it was needed.
With the Downfall of Númenor came the end of classical Adûnaic. The study and preservation of the language was neglected by the Exiles of Númenor, because they associated it with the rebellious and repressive Númenórean Kings.
However, this debased tongue, spread from the early Númenórean sailors and colonists, continued to spread as their settlements increased in size and influence and met more peoples, who came under their rule. Those Men of different kinds used this language as a lingua franca among them. This process became of general importance after the Realms in Exile; from Eriador to Gondor the tongue became widely current, being adopted both by inhabitants and incomers, eventually becoming their native language, which they called Westron, widely spoken during the Third Age.

Adûnaic is an Anglicized name of the language. It's unknown how it would be called in the own language, but later Westron speakers called their language Adûni. Some hypothetical words have been modeled after Nimriyê ("Elvish"): Adûnaiyê, Adûnâyê and Adûnâiyê.
