My analysis of Adûnaic phonology is based entirely on “Lowdham’s Report on the Adûnaic Language” written by Tolkien in the
1940s (SD/414-440). Tolkien described the phonological history of the language from Primitive Adûnaic to Classical Adûnaic in great detail, but provided few explicit examples. The analysis of Adûnaic’s phonetic rules presented
here is based largely on Tolkien’s description of the rules rather than the development of individual words. As such, there
is little reason to look at the analysis here, since it is basically a rehash of the original source material, but I included
it for the sake of completeness. It can also be considered a proof of concept for how phonetic analysis is handled in this
lexicon, since Adûnaic is the first language I analyzed.
