Phonology

 * 1) only occurs in Russian or Ukrainian loans, often only in educated speech
 * 2) only in foreign borrowings, esp. Belorusian
 * 3) there is free variation between retroflex and postalveolar pronunciations of these phonemes
 * 4) allophones of the post-alv series before soft vowels and in the clusters ɕtɕ & ʑdʑ.
 * 5) allophone of [lʲ] before iotated back vowels
 * 6) typically only in foreign borrowings in educated speech, otherwise it's a fricative [γ]. Also after nasals

Note that this is a phonemic chart, a more phonetic analysis is given below As can be inferred from the chart, there is vowel reduction which is overall not as extensive as Russian but more so than Belorussian.
 * 1) Functionally equivalent to <э> after velar consonants
 * 2) chiefly in dialects heavily influenced by Russian

Long vowels are a result of the coalescence of a vowel (or two vowels) and a glide. Thus the masculine adjective endings -ий and -ый are pronounced iː and ɨː. Due to sound changes concerning the letters л & в, the ToloT and TeleT series also produce long vowels, ie PSl solma > Jsch соўма ['soːmə], cf Russ солома, and PSl melti > Jsch моўть [moːc], cf Russ молоть.
