Old Týrýng language

The Old Týrýng language was the language of the Empire of Týrýng until around ~350 AEKE, when it got replaced by Current Týrýng.

Vowels

 * The original /a aː/ got fronted to [æ æː] in most environments, while in a few others, it became [ɑ ɑː]
 * /a aː/ became [ɑ ɑː] after the labio-velar /kʷ kʷʰ gʷʱ ɣʷ/ and the murmured /bʱ dʱ d͡zʱ ɟʱ gʱ/, as well as before [ł]. In every other environments, /a aː/ became [æ æː].

Consonants

 * The palatal /ɟʱ cʰ c/ became /d͡zʱj t͡sʰj t͡sj/ before all vowels but /i iː/, and plain /d͡zʱ t͡sʰ t͡s/ before /i iː/
 * /ɣʷ/ became [w], /ɣ/ was completely removed in all positions
 * /ʋ/ became [w]
 * /ɺ~ł/ changed depending on the environment:
 * Coda-position /ł/ became vocalized to [w]
 * Onset /ɺ/ lost its lateral quality and became [ɾ]
 * The original voiceless unaspirated plosives /p t t͡s k kʷ/ gained an allophonic medial voicing to [b d d͡z g gʷ]
 * The original voiceless aspirated plosives /pʰ tʰ t͡sʰ kʰ kʷʰ/ became fricatives /ɸ θ s x/. /θ/ then merged with /s/ very soon after this consonant shift.
 * The original voiced aspirated plosives /bʱ dʱ d͡zʱ ɟʱ gʱ gʷʱ/ became voiceless aspirated /pʰ tʰ t͡sʰ kʰ kʷʰ/.

Phonology
Each syllable consists of:
 * An optional initial consonant
 * A mandatory vowel
 * An optional coda-position glide or consonant: /j/, /w/, /p̚/, /t̚/, /k̚/, /m/, /n/ or /ŋ/

Consonants

 * The unreleased stops /p̚ t̚ k̚/ and the velar nasal /ŋ/ appeared only in the coda position.
 * [ɲ t͡ɕʰ t͡ɕ~d͡ʑ ɕ] were allophones of /n t͡sʰ t͡s s/ before the glide /j/ and the vowels /i iː/
