Many people confuse Bulgarian and Russian because both languages use the Cyrillic alphabet.

However, these two Slavic languages are completely distinct and have major grammatical differences.

Knowing how they differ will help you learn either language much faster.

I’ll break down the biggest differences in their alphabets, grammar rules, and vocabulary below.

The alphabet differences

Bulgarian and Russian share the Cyrillic alphabet, but they don’t use all the exact same letters.

Russian has 33 letters in its alphabet, while Bulgarian only has 30 letters.

Russian uses letters like Ы, Э, and Ё which don’t exist in Bulgarian at all.

Bulgarian relies heavily on the letter Ъ, known as “Er golyam”.

In Russian, Ъ is simply a “hard sign” that separates syllables without making its own sound.

In Bulgarian, Ъ is an actual vowel that sounds very similar to the “u” in the English word “but”.

For example, the country of Bulgaria is spelled with this letter.

The grammar of cases

The absolute biggest difference between Russian and Bulgarian is how they handle nouns.

Russian uses a complex case system with six different grammatical cases.

This means Russian word endings change constantly depending on their role in a sentence.

Bulgarian is unique among Slavic languages because it has almost entirely lost its case system.

Instead, Bulgarian uses prepositions to show relationships between words, just like English does.

This makes Bulgarian noun grammar significantly easier for English speakers to grasp.

You just learn the noun once and plug it into your sentences.

Definite articles

Russian doesn’t have definite articles like “the” or indefinite articles like “a” or “an”.

Bulgarian has definite articles, but they work differently than they do in English.

Bulgarian uses postfixed articles, meaning you attach “the” directly to the end of the word.

For example, the word for “man” is мъж.

To say “the man”, you add the article to the end to make it мъжът.

Here’s a quick comparison showing how articles function in these languages:

Vocabulary and false friends

Bulgarian and Russian share a massive amount of similar vocabulary due to their Slavic roots.

If you know basic greetings in one language, you can often recognize them in the other.

However, you must watch out for “false friends” between the two languages.

False friends are words that look and sound identical but mean completely different things.

If you tell a Russian driver to go направо, they’ll turn to the right.

If you tell a Bulgarian driver to go направо, they’ll drive straight ahead.

Here are a few common false friends you should memorize:

Which language should you learn?

Both languages are incredibly rewarding to study, speak, and read.

Bulgarian is highly recommended for beginners because its lack of cases makes the grammar much more approachable.

You’ll spend less time memorizing noun ending charts and more time actually speaking.

Once you learn Bulgarian, the transition to understanding other Slavic languages becomes much easier.
