In Bulgarian, Macedonian, Russian, and Serbian, the Cyrillic alphabet is also known as azbuka, derived from the old names of the first two letters of most Cyrillic alphabets (just as the term alphabet came from the first two Greek letters alpha and beta).
在保加利亚、马其顿、俄罗斯和塞尔维亚，西里尔字母还被称作azbuka，出自许多西里尔字母表前两个字母的旧称（就像alphabet来自于希腊字母的前两个alpha和beta）。
