Answer:
The Greek, Egyptian, and Hebrew languages were used to compose the Cyrillic alphabet.
Step-by-step explanation:
The Cyrillic alphabet is a group of alphabets used to write seven Slavic languages (Russian, Belarusian, Bulgarian, Macedonian, Serbian, Ukrainian and Montenegrin) and several non-Slavic languages, mainly in the former Soviet Union (including Kazakh, Uzbek, Kyrgyz, Mongolian, Tajik, Turkmen, Chechen and Kildinese). The alphabet has previously been used for several languages, where alphabets were changed, such as Romanian (until 1860), Azerbaijani and Moldavian. Like the Latin alphabet, most of the languages have their own letters that do not necessarily have to be in other languages.
