Serbian vs Bulgarian Alphabet: 30 Letters Each, 6 Different
| Bulgarian | Serbian | |
|---|---|---|
| Letters | 30 | 30 |
| Shared letters | 24 | 24 |
| Only in this alphabet | Й Щ Ъ Ь Ю Я | Ђ Ј Љ Њ Ћ Џ |
| Also written in Latin? | Only as transliteration | Yes, a full Latin alphabet |
In the Serbian vs Bulgarian alphabet comparison, both have 30 Cyrillic letters and share 24. Only Bulgarian has Й Щ Ъ Ь Ю Я; only Serbian has Ђ Ј Љ Њ Ћ Џ. Serbian also has an official one-to-one Latin alphabet, while Bulgarian is written only in Cyrillic.
The Serbian vs Bulgarian alphabet question has a neat answer: both have 30 Cyrillic letters, and 24 of them are the same. Each alphabet then has six letters the other lacks. Bulgarian has Й, Щ, Ъ, Ь, Ю and Я; Serbian has Ђ, Ј, Љ, Њ, Ћ and Џ.
The two languages are both South Slavic, but they solved spelling in different ways. Serbian Cyrillic follows a strict one-letter-per-sound design. Bulgarian kept more of the older Cyrillic tradition, including letters that combine two sounds, such as я for “ya”.
Serbian vs Bulgarian alphabet at a glance
The 24 shared letters are: А Б В Г Д Е Ж З И К Л М Н О П Р С Т У Ф Х Ц Ч Ш. They are pronounced in much the same way in both languages, so a Bulgarian reader can sound out most Serbian words and the reverse.
The six letters only Serbian has
Serbian Cyrillic in its modern form was finalized by the reformer Vuk Karadžić, whose Serbian dictionary appeared in 1818; the alphabet was officially adopted in 1868. He added letters so that every sound would have exactly one letter. Two of them, Љ and Њ, are ligatures of л and н with the soft sign; Ј was borrowed from the Latin alphabet.
| Serbian letter | IPA | Close English sound | Serbian Latin |
|---|---|---|---|
| Ђ ђ | [dʑ] | soft “j”, between “j” in “jeans” and “dy” | Đ đ |
| Ј ј | [j] | “y” in “yes” | J j |
| Љ љ | [ʎ] | “lli” in “million” | Lj lj |
| Њ њ | [ɲ] | “ny” in “canyon” | Nj nj |
| Ћ ћ | [tɕ] | soft “ch”, lighter than “church” | Ć ć |
| Џ џ | [dʐ] | hard “j” in “jam” | Dž dž |
The last column matters. Serbian is written in two scripts, Cyrillic and Gaj’s Latin alphabet, and the two map one to one. Serbia’s constitution of 2006 names Cyrillic as the script in official use, while Latin remains common in everyday life, advertising and online.
The six letters only Bulgarian has
Bulgarian uses letters that Vuk’s reform removed from Serbian, or never had. Here is how Serbian handles the same sounds:
| Bulgarian letter | What Serbian does instead |
|---|---|
| Й й | Serbian uses ј: Bulgarian май vs Serbian мај |
| Щ щ | Serbian has no sht letter; compare Bulgarian нощ with Serbian ноћ (night) |
| Ъ ъ | Serbian has no schwa vowel |
| Ь ь | Serbian folds softness into љ and њ |
| Ю ю | Serbian writes ју or љу: Bulgarian любов vs Serbian љубав (love) |
| Я я | Serbian writes ја: Bulgarian ябълка vs Serbian јабука (apple) |
The biggest real difference is ъ. In Bulgarian it is a vowel, roughly the “u” in “but” ([ɤ]), and it is everywhere: България (Bulgaria), път (pat). Serbian has no such vowel, so it needs no letter for it. For the full story of this letter, see the Bulgarian letters overview.
Serbian vs Bulgarian alphabet in real words
Related words show the pattern clearly. Where Bulgarian writes щ, Serbian often has ћ. Where Bulgarian writes я or ю, Serbian uses ј or a soft consonant letter.
| English | Bulgarian | Serbian |
|---|---|---|
| night | нощ | ноћ |
| book | книга | књига |
| horse | кон | коњ |
| love | любов | љубав |
| apple | ябълка | јабука |
| Wednesday | сряда | среда |
The play buttons read the Bulgarian words only. Note that some pairs look alike but are pronounced differently: Bulgarian книга and Serbian књига differ in the softness of the n.
Why the two alphabets drifted apart
Both alphabets descend from the same medieval Cyrillic, which spread from the First Bulgarian Empire to Serbia in the Middle Ages. For centuries Serbian and Bulgarian scribes used similar letter sets, including letters both later dropped.
The split came with 19th- and 20th-century reforms. Vuk Karadžić rebuilt Serbian spelling on a strict “one sound, one letter” principle, dropping я, ю, ъ and ь. Bulgarian took a more conservative route: an alphabet of 32 letters became standard in the 1870s, and the 1945 reform cut it to the current 30. That is why the Serbian vs Bulgarian alphabet differences look so systematic today. The history of the Bulgarian alphabet covers the Bulgarian side in detail.
Letterforms: both have local shapes
Bulgarian and Serbian share another trait: both have local letterforms that differ from Russian. Serbian italic and handwritten б, г, д, п and т take their own shapes, while Bulgarian typography often uses rounder lowercase forms for letters such as д, л and т. Microsoft’s OpenType specification mentions both languages in its description of the locl (localized forms) feature. Details are on our Bulgarian Cyrillic page.
Reading Serbian if you know the Bulgarian alphabet
If you can already read Bulgarian, Serbian Cyrillic takes an afternoon. Learn the six new letters, remember that ј replaces й, and you can read signs in Belgrade. The reverse is just as manageable: a Serbian reader needs ъ, щ (“sht”) and the combined letters ю and я. Our learning plan starts from the letters you already know.

Common mistakes
- Using Serbian ј in Bulgarian. Bulgarian never uses ј. Write й, я or ю: мая, not “маја”.
- Reading Bulgarian щ as Serbian ћ. Щ is “sht”, two clear sounds.
- Skipping ъ. Serbian speakers sometimes write Bulgarian words without ъ. It is a full vowel and must be written.
- Assuming Bulgarian has a Latin alphabet too. Bulgarian is written only in Cyrillic. Latin is used only for transliteration.
- Mixing up X and Х. Both languages use х for the “kh” sound, never Latin x.
Frequently asked questions
Are the Serbian and Bulgarian alphabets the same?
No. Both have 30 Cyrillic letters and share 24, but each has six letters the other does not use.
What letters are in Serbian but not Bulgarian?
Ђ, Ј, Љ, Њ, Ћ and Џ. They were added or adapted in Vuk Karadžić’s reform so that every sound has one letter.
What is the main difference in the Serbian vs Bulgarian alphabet?
Bulgarian has the vowel letter ъ and combined letters such as я and ю; Serbian instead uses ј and soft-consonant letters like љ and њ.
Can a Bulgarian read Serbian Cyrillic?
Mostly, yes. Learning six letters is enough to read Serbian aloud, though understanding the language is a separate matter.
Does Bulgarian use the Latin alphabet like Serbian?
No. Bulgarian uses only Cyrillic; Latin appears only as transliteration, for example on passports.
