Cyrillic is literally greek+glagolitic and it was partly a diplomatic creation of the Eastern Roman Empire(aka Byzantine Empire), in order to bring the slavs culturally closer to them.
Russians have nothing to do with it, other than them claiming they are the continuation of Eastern Roman Empire, something which is kinda laughable but whatever dont let your dreams be dreams.
“Liberte” and “egalite” are latin words. “Electrolyte” is greek.
Mixing greek and latin is an abomination and we should put a stop to it. Say no to those mixed greek+latin words, it is an affront to God.
