The creation of the Evenki alphabet began in the 1920s. In May 1928, researcher G. M. Vasilevich (ru) prepared for the Evenk students who studied in Leningrad the “Memo to Tungus-vacationers”. It was a small textbook duplicated on the glass. It used the Vasilyevich Evenki alphabet on a Latin graphic basis. A year later, she compiled the “First Book for Reading in the Tungus Language” (Әwәnkil dukuwuntin). This alphabet had the following composition: Aa Bb Çç HH Dd Ӡӡ Ee Әә Gg Hh Ii Kk Ll Mm Nn Ŋŋ Oo Pp Rr Ss Tt Uu Ww Yy; it also included diacritical marks: a macron to indicate the longitude of the sound and a sub-letter comma to indicate palatalization.
