Old Shár language

Old Shár was the stage of the Shár language between 3500 BEKE and around 100 AEKE.

Syllable structure
In Old Shár, a syllable normally consisted of:
 * (Optionally) An initial consonant, or a consonant + glide cluster.
 * The velar glide could only exist after the velar consonants
 * The palatal glide could exist after any consonant
 * (Mandatory) A vowel
 * (Optionally) A final glide or a coda-consonant

Initials

 * The actual status of is unknown. It could have been an alveolar trill, alveolar approximant  or retroflex approximant  like in most current variants of Shár. Most likely, it was a trill in an early stage of the language, but became an approximant later.
 * The voiced fricative was probably much more approximant-like, as it later on merged with
 * was bilabial. It later became a labiodental.

Between Early Old Shár and Late Old Shár, various initials have changed:
 * Voiced and unaspirated voiceless stops merged, yielding one unaspirated series that is voiceless initially, voiced medially.
 * At the time, medial was still a voiceless . It gained the intervocalic voicing only after the Old Shár period has ended.
 * The postalveolar series and palatal series  merged, yielding a new shibilant affricate series
 * became
 * merged with
 * became instead
 * became

Finals
In Old Shár, every final consisted of a vowel (chart below), and optionally a glide or a coda-consonant. After the Old Shár period ended, the finals became tones, for example,  became.

There were some limitations to the positions in which these vowels occour.

For example, occurred exclusively after alveolar sibilants and the rhotic, and could only appear in open syllables or before. In contrast, was absolutely forbidden in open syllables or before, occurring only before the codas. In a way, one could say that and  were in complementary distribution, except that  could occur after any kind of consonant, not just alveolar sibilants and. Similarly to, was also disallowed in open syllables, being shifted to  in that kind of context.
