Notes.
In most languages (except Tur. and Gag.) > m- before a following nasal, with slightly differing rules. The same is true for (*-p-) > *-b- > *-m- in the second syllable.
Voicing occurs on morpheme boundaries and occasionally - in cases
of morphological reanalysis (cf. cases like Tat. sipir- / sibir- to Sweep', where 4r- could have been re-analysed as a causative suffix).
Probably dialectal variants, occasionally rendered in orthography.
Depending on vocalic environment.
After labialized vowels.
Depending on vocalic environment and with dialect variation.
See more details in PP.
*t-, *d-, *c- > c- in front of -i-, 4-.
-d- in the intervocalic cluster *-rt- and in the beginning of auxiliary
morphemes.
Occasionally recorded as voiceless in Verbitskiy's materials.
-d- in the beginning of auxiliary morphemes.
*-t-, -c- > -3- in front of -i-, 4-.
*d- > t- before the following voiceless -x-.
Variation in dialects and recordings.
Variation in dialects.
*s- > s- in front of -i-, 4-.
Distribution unclear.
*-s- > -z- in front of 4-, 4-.
In some dialects lost with compensatory vowel nasalization.
In dialects also 3-.
In dialects also variants 3-, z- before narrow vowels.
Normally j before a, o, 6, u, ii, e; 3 before e, i, i; but the distribution may be additionally somewhat confused because of dialect variation.
In most languages is not distinguished from *-j-, but causes nasalization of initial *b- > m-.
Frequently causes nasalization of initial *j- > n-.
Before back vowels voiceless *k- and voiced *g- cannot be distinguished in PT; in this position we usually write *K-.
Depending on whether the following/preceding vowel is front or back.
Depending on whether the following vowel is wide or narrow.
Depending on whether the original following/preceding vowel was front or back.
Depending on whether the original following/preceding vowel was front or back. *K- > j- before an original diphthong.
Reconstructable only before front vowels.
Devoicing of final *-g is a characteristic feature of the Karluk languages; however, both in Uzbek and in Uighur it occurs irregularly, depending probably on morphological derivational analogies.
In the end of a polysyllabic word. Details see in PP.
Variation in dialects; in case of disappearance nasalization is preserved on the preceding vowel.
In dialects also -g- or -0-.
In some combinations and in the end of a polysyllabic word.
In combinations with palatals - n, in some vocalic environments - j.
Distribution not quite clear.
