Antanath Halfling language

The Antanath Halfling language is a standardized variety of Halfling, based on the Eastern dialects. It is more than just a standardized variety of Halfling - some would argue that it's a constructed language, as, in addition to being phonologically more conservative than its western counterpart (which is somewhat more "naturalistic"), it also aims to reintroduce elements of the oldest forms of Halfling known.

Consonants

 * The consonantal system of Halfling traditionally divides consonants into two categories: Broad and Slender. The earlier can only appear before and after back and central vowels (never before or after front vowels), while the latter can appear before and after any vowel.
 * There are two exceptions to this rule: and, despite being classified as Broad consonants, also appear before front vowels.
 * The voiced fricatives originated from the postvocalic lenition of the corresponding stops, therefore do not appear word-initially or after nasal vowels in native Halfling words. They do appear word-initially and after nasal vowels in loanwords though.
 * and are not distinguished anymore in any variant of Halfling. Both of them are generally pronounced as an approximant  in all positions.
 * Under the influence of other local languages (such as High Elven and Etrandish), are often pronounced as labiodental  rather than the recommended bilabial.
 * cannot appear word-initially or geminated. Both word-initially and when geminated, they are replaced by
 * can only appear word-initially, or between two vowels. It cannot appear after nasal vowels.
 * Nasal vowel +  clusters are usually pronounced as nasal vowel +   clusters instead. For example,  and  can be respectively pronounced as  and.

Vowels

 * Because Antanath Halfling intends to reconstruct the "purest and oldest form of halfling", it preserves the open front vowels, but lacks the front rounded vowels of the Eastern Halfling dialect group it is based on (they appear only in loanwords to begin with), replacing them with  in any of the loanwords that aren't replaced by native neologisms.
 * Nasal vowels lose their nasalization if they are proceeded by a nasal+vowel cluster.
 * Nasal vowels tend to be dissimilated into vowel + nasal clusters before stop consonants and rhotic consonants, turning, , , , , , , into , , , , , , ,  respectively. This doesn't effect nasal vowels word-finally or before other kinds of consonants.
