Goblin languages

The Goblin languages is a language family associated with the race Goblins, having been traditionally spoken by them.

Proto-Goblin
The Proto-Goblin language only had 5 vowel phonemes, 12 dipthongs and 14 consonant phonemes , no vowel length distintion, no gemination, no tones, with the following details: Not all of the consonants could appear in all positions:
 * were true mid
 * were either lamino-alveolar or denti-alveolar
 * were apico-alveolar . could have also been possibly uvular
 * was alveolo-palatal
 * can only appear between two vowels in native vocabulary. It can also appear word-initially in loanwords.
 * can appear in all positions, except word-initially. Not even in loanwords can it appear word-initially.
 * Word-initial consonant clusters were not tolerated.
 * Vowel clusters are not tolerated, and are broken up by an epenthetic in loanwords. The only exceptions are clusters that start with or end with  or, which were converted into diphthongs.

Koblin †
Spoken formerly in what is now Artaburro, the language is virtually extinct, as the Artaburran Goblins were marginalized to the point of near-extinction, the remnant expelled into lands that cannot support large populations.
 * At first, the proto-Goblin and  merged as a new phoneme, while  remained untouched.  also softened to.
 * The original proto-Goblin diphthongs became, while  remained untouched
 * Some time around or before the proto-Elven colonization of Artograch (2500-2000 BEKE) shifted to,  became ,  became . Simultaneously,  became ,  became ,  became ,  became.
 * During the last centuries of the language's virtual existence, short became  and the formerly established vowel length distinctions were lost, resulting in a vowel inventory of
 * Around 270 AEKE, the langauge went virtually extinct. What remained of the survival speakers was expelled into inhospitable territory. If the descendants of the survivors still linger on, the number of speakers of this language may be in a few hundreds instead of zero.

The Koblin endonym ->  gave rise to the Proto-Elven exonym  for the Goblins. This would in turn evolve into:
 * Proto-Human "gablinaz", giving rise to...
 * Old Etrandish "gæfln", evolving into Middle Etrandish "yeflen" , though it has been largerly replaced by the "goblin" and "cobold" (see below)
 * Old Hulran "gefln", evolving into Etrancoasti "gevlen" , though it has been largerly replaced by the "goblin" and "cobold" (see below)
 * Wood Elven "goburin"
 * Archaic High Elven "goblinos / goblina / goblinom", evolving into the Classical High Elven "goblinus / goblina / goblinum"
 * Middle High Elven "govlénó / govléna", eventually replaced by Classicized / re-learned "goblinó / goblina"
 * Etrandish "goblin", and from it Etrancoasti "goblin"

Kobold
Spoken in Brutang, this language continues to thrive. Nearly all native speakers are bilingual in the Orcish language.
 * The original became, while  remained untouched, pronounced as.
 * The original diphthongs became.
 * coalesce into new labio-velar and palato-velar sounds . The palato-velar eventually evolve into
 * Loanwords from Orcish introduced into the language
 * At one point, the voiceless stops became aspirated.
 * Unlike in Orcish, the voiced stops never lost their voicing, remaining fully voiced in all environments.

The Kobold endonym ->  gave rise to the Middle Etrandish "cobold", being retained into current Etrandish  and the Etrancoasti "cobold".

Gaildaurn / Geldorn
Spoken in Keldorn.
 * The original diphthongs become
 * The vowel length distinctions are lost later on, temporarily resulting in a 9-vowel system
 * This 9-vowel system is broken up later, by breaking into . This results in a five-vowel system.
 * The original voiced stops become become voiceless  - remaining voiced only medially -, while the original voiceless  became . The aspirated stops become strongly aspirated, while the unaspirated ones gain a slight aspiration when initial.

The Geldorn endonym (their own word for goblins, themselves), "gaildaurn" ->  ->  would give rise to the Keldorni Etrandish name for the island - and name of the state - "Keldorn", giving its name to the Republic of Keldorn as well. It is important to note that Keldorni Etrandish still uses the words "goblin" and "cobold" for the race itself.
