Рефлексы праславянских сочетаний типа *tьrt, *tъrt, *tьlt, *tъlt в Выголексинском сборнике

The aim of this work is to examine reflexes of the Proto-Slavic compounds*t?rt, *t?rt, *t?ltand*t?lttype in the manuscript Vygoleksinskij Sbornik(Collection) which was copied in Old Russian language area at the end of the 12th century. I have found 4 writing methods of the examined reflexes: 1. Old Russian type,309 examples,e.g.v'rh=, d=lgago; 2. two-yer writing method,52 cases,e.g.d'r'xati, m=l=;[;3. reflecting vocalization of the reduced vowel,16examples, e.g.priderxa s/,polnu; 4. mixed type with vocalization and one yer, 4 cases, e.g. v=zver'goh=, s=vol=k=. I haveconcluded that the manuscript reflects the whole russification of the examined reflexes. The examples of the vocalization refer to the fact that the manuscript must have been copied only after 1164, after the writing of the famous Dobrilo Gospel. The cases of the intersyllable assimilation in the root(-)sk'rb-can localize the place of the manuscript's genesis in the southern part of the Old Russian area
