The Black Speech (S. Morbeth) was a language devised by Sauron during the Dark Years to be the sole language of the servants of Mordor, intended for replacing the many different varieties of Orcish and other languages, though in practice if was only used as a ritual-language.It was loosely based on the older Melkian and closely related to the oldest angbandian-orcish which in return were derived from Valarin and debased Primitive kwendian[1] see:


Black Speech and Mordorian Orcish seem to have lacked the letters c, ch, e, j, s. In BS c turns to k, ch to kh, j to y and s to sh or zh. It is unknown if e was omitted or replaced by a different syllable, it is also not entirely clear if the letters f, q, v and x existed in BS as only Fh is attested and q seems to have been substituted by ku, v by w or fh and x by ks, though it is not known is this was true for all mordorean and derived dialects.

Black Speech´s main source, Melkian seems to have still known the letters s, v and x.
