Black Speech Wordlist

Orc-names, the meanings of which are unknown, are excluded. DBS means "debased Black Speech" and in effect marks words from the curse of the Mordor-orc, except in the case of sharkû. Of course, some of these words may not differ from their form in pure Sauronian Black Speech. We shall never know.
          agh "and"
          ash "one"
          -at infinitive suffix, or possibly a specialized "intentive" suffix indicating purpose: Ash nazg durbatulûk "one Ring to rule them all"
          bagronk (DBS) "cesspool", possibly bag+ronk "cess+pool"
          búbhosh (DBS) "great"
          búrz "dark", (isolated from Lugbúrz, q.v.), burzum "darkness"
          dug "filth", tentatively isolated from pushdug, q.v.
          durb- "rule", infinitive durbat, only attested with suffixes: durbatulûk "to rule them all". The verb durb- is remarkably similar to Quenya tur- of similar sense.
          ghâsh "fire" (stated to be derived from the Black Speech, may or may not represent Sauron's original form of the word)
          gimb- "find", infinitive gimbat, only attested with a pronominal suffix: gimbatul, "to find them"
          glob (DBS) "fool"
          gûl "any one of the major invisible servants of Sauron dominated entirely by his will" (A Tolkien Compass p. 172). Translated "wraith(s)" in the compound Nazgûl, "Ringwraith(s)".
          hai "folk", in Uruk-hai "Uruk-folk" and Olog-hai "Troll-folk"; cf. also Oghor-hai.
          ishi "in", a suffixed postposition: burzum-ishi, "in the darkness".
          krimp- "bind", infinitive krimpat, only attested with a pronominal suffix: krimpatul, "to bind them"
          lug "tower". Isolated from Lugbúrz, q.v.
          Lugbúrz the Dark Tower, Sindarin Barad-dûr (Lug-búrz "Tower-dark")
          nazg "ring": ash nazg "one ring", Nazgûl "Ring-wraith(s)"
          Nazgûl "Ring-wraith(s)", nazg + gûl (q.v.)
          Oghor-hai "Drúedain" (UT:379; this may or may not be pure Black Speech)
          olog a variety of Troll apparently developed by Sauron. Olog-hai "Olog-people".
          pushdug (DBS) "dungfilth", possibly push+dug "dung+filth"
          ronk (DBS) "pool", tentatively isolated from bagronk, q.v.
          skai (DBS) interjection of contempt
          sha (DBS) interjection of contempt
          sharkû (DBS?) "old man"
          snaga "slave" (May be DBS.) Used of lesser breeds of Orcs (WJ:390).
          thrak- "bring", infinitive thrakat, only attested with suffixes: thrakatulûk "to bring them all"
          u (DBS) "to"
          -ûk "all", suffixed to pronominal suffixes: -ulûk, "them all"
          -ul pronominal suffix "them".
          -um "-ness" in burzum "darkness".
          uruk a great variety of Orc. According to WJ:390, Sauron probably borrowed this word "from the Elvish tongues of earlier times".

Кое-что о произношении:

The Black Speech possesses the plosives b, g, d, p, t, k, the spirants th, gh (and possibly f and kh, attested in Orc-names only), the lateral l, the vibrant r, the nasals m, n, and the sibilants s, z, sh. This may not be a complete list, given our small corpus.

The vowels are a, i, o, u; the vowel o is stated by Tolkien to be rare. The Black Speech does not seem to use e. Long â and û are attested (the latter is also spelt ú, but "An Introduction to Elvish" p. 166-167 is probably right in assuming that this is simply inconsistent spelling on Tolkien's part). There is at least one diphthong, ai, and au occurs in an Orc-name. (As it is uncertain what language such names belong to, they are not further dealt with here.)

What, then, was perceived as unpleasant by the Elves? It is stated that the Orcs used a uvular r, like the R that is common in French and German, and that the Eldar found this sound distasteful. It has been suggested that this was the standard pronunciation of r in the ancient Black Speech ("An Introduction to Elvish" p. 166). The Black Speech also had certain consonant clusters that did not appear in contemporary Sindarin: sn, thr, sk initially and rz, zg finally. Whatever the cause, the language was generally perceived as singularly harsh [...].
