What is perhaps most curious about Imrazôr is his Adûnaic name. Adûnaic was the common tongue among the Dunedain of Númenór in the SecondAge, and was therefore widely spoken throughout the various Númenórean dominions in Middle-earth. Although the language eventually developed into Westron (the Common Speech), under the influence of Sindarin and Quenya (and other Elvish and Mannish tongues), Adûnaic in its pure form supposedly disappeared after the Downfall--though undoubtedly it survived and flourished for many centuries among the Black Numenoreans. In any case it came to represent Númenór at its worst, under the influence of Sauron: the rejection of Elves and of the West, persecution of the Faithful, Melkor-worship, and defiance of the Valar. For this reason it is highly unlikely that Adûnaic would have been spoken anywhere in the Realms in Exile, and it is even more unlikely that any Dunadan of Gondor or Arnor would take an Adûnaic name--certainly not by the second millenium of the Third Age.

Was Imrazôr, then, a Black Numenorean? J. E. A. Tyler, in his Complete Tolkien Companion, describes Imrazôr as a "Númenórean mariner", so it is quite likely that he came to dwell in Belfalas from elsewhere: probably Umbar. Umbar had been taken decisively by Telumehtar Umbardacil of Gondor in 1810. If it could be supposed that Imrazôr flourished sometime between 1850 and 2050, he could have spent the first 50 years of his life (or thereabouts) in Umbar, and operating out of it as a mariner, under Gondor's rule. Given that Gondor was never able to maintain a foothold in Umbar for more than a few centuries at a time, it is quite conceivable that the use of Adûnaic names (if not the language itself) persisted in a territory which never shook off its Black Numenorean character until the WotR.

Black Numenorean or no, Imrazôr seems to have been friednly enough with Gondor to flee there when Umbar was re-taken by the Southrons and the Corsairs (this is, of course, speculation). Although it is not recorded whether he adopted an Elvish name himself in Belfalas, he did name his children Galador and Gilmith.
