西スラヴ語群
The Latin script also came into use for writing the West Slavic languages and several South Slavic languages, as the people who spoke them adopted Roman Catholicism. The speakers of East Slavic languages generally adopted Cyrillic along with Orthodox Christianity. The Serbian language uses both scripts, with Cyrillic predominating in official communication and Latin elsewhere, as determined by the Law on Official Use of the Language and Alphabet.
