The article gives an analysis of the manuscript Udmurt grammar called ”Kраткiя правила вотскаго языка” (Short rules of the Votic language). A cursory examination may give the impression that the manuscript is one of the variants of the book ”Сочиненiя принадлежащiя къ грамматикѣ вотскаго языка” published in 1775. Although the graphics and spelling elements of the printed and handwritten grammars coincide almost completely, there are quite a number of words differing in spelling. Varied design of same words can be explained, in some cases, by inconsistent spelling, in others — by dialectal differences in pronunciation and a different fixation of the letter. Some differences are also observed in the structure of the written monuments.
