====== Internal history of the Black Speech (fictional) ======
Analysis of the Ring Verse inscription((published in PE 17)), some geographical and personal names gives us such distinct features as:
  * Adjectives and other descriptive words are placed //after// the word they describe, but this rule is not very strict even for Tolkien's sources;
  * Nouns do not have plural form, but verbs and pronouns //possibly// do;
  * Subjective personal pronouns are //prefixed// to verbs;
  * Objective personal pronouns are //suffixed// to verbs;
  * The verb have special form combining features of infinitive, participle and gerund.

If the [[Alexandre Nemirovsky]]'s [[hurrian_hypothesis|hypothesis]] about connection between [[Black Speech]] and Hurrian languages is right then we can assume following things to be typical for early Black Speech:
  * Nouns and verbs have numerous grammar forms expressed by long chain of suffixes;
  * //Post//positions and case suffixes are used instead of prepositions;
But the significant feature of Hurrian language is [[wp>Ergative–absolutive_language|Ergative]] alignment with SOV (Subject--Object--Verb) sentence structure, which has no evidence in known Tolkien's material.

[[Nûrlâm]] is considered to exist in time between Classical Black Speech and orcish dialects (Svartiska, Shadowlandian, etc.), and following changes occurred in it:
  * Restricting number of cases to 15 and make others standalone postpositions;
  * Added prepositions and more prefixes.
However some hypothetical features of Classical Black Speech are used for [[archaic style]] of Nûrlâm.

Taking in account rules of other dialects, their real use and common mistakes, modern Black Speech has tendency to copy English grammar and syntax:
  * Shift from agglutinative to analytic type of language, replacing long chain of suffixes and clitics with words written separately, which order determines the sense and grammar form;
  * Reducing the number of noun cases to 4 or even denying them all;
  * Adding category of number for nouns, pronouns and adjectives;
  * Pronouns restricted to 2 cases;
  * Replacing postpositions with prepositions;
  * Adjectives, adverbs, pronouns start being spelled before the words they describe;
  * Adding small hints of animacy and gender categories;
  * Infinitives merged with gerundives taking suffix //-at//, they become used for 3rd person or even all verbs.

Nûrlâm dialect supports these tendencies too but considers them as [[syntax_analytic|colloquial]] or dialectical.

===== Relation to other languages of Arda =====
While small corpus of Classical Black Speech contains at least two words from Valarin, a mother-tongue of Sauron who was the author of Black Speech, it has also words from various [[elven_languages|languages of Elves]]. As it's believed that orcs were made from captured, tortured and corrupted elves (at least until greater Uruk-hai were bred), Elvish influence on languages is obviously natural. So if we group languages or Arda into groups and families as for real ones, Black Speech will definitely belong to Elvish family.

Orcs used Common Speech (Westron) in communication between different breeds and tribes as it stated in LOTR, but no traces of it found in Debased Black Speech, which still has a lot of elvish words.

[[Angband Orcish]] of 1st Age appeared before Sauron created Black Speech, and it was almost entirely a corrupted version of Sindarin or more closely it's earlier version (in real-word terms) called Noldorin. 

Neo-Black Speech dialects continue to actively borrow words from various elvish languages, however larger part of their [[Lexicon]] consists of unique words.
