Serbian has two alphabets for the same language
Modern Serbian is written in both Cyrillic and Latin. The words and grammar do not change when the script changes: voda and вода both mean “water.” Once you know the matching letters, moving between the two scripts becomes a reading skill rather than a translation problem.
The alphabet is highly phonetic. Each letter normally represents one sound, so spelling is much more predictable than in English. The Latin combinations lj, nj, and dž each become one Cyrillic letter: љ, њ, and џ.
Do not wait until you have memorized all 30 letters. Learn a small group, read several words with those letters, and then add the next group.
Start with words you can compare
Read each Latin form, then look for the same sounds in Cyrillic. Some letters look familiar, while others need deliberate practice.
A simple Cyrillic practice plan
Ten focused minutes is enough for one session. Accuracy matters more than speed at first. As the shapes become automatic, your reading speed will rise naturally.
