How to Say “C” in Russian

си
si[sʲi]
Russian speakers call the Latin letter C си, the name they use when spelling out English words or Latin abbreviations letter by letter.
Russian has its own alphabet, so the Latin letter C has a borrowed name, си, taken from its English pronunciation. You hear it when someone spells an email address or a brand name aloud. The same name is used for the C programming language, usually written Си. The Cyrillic letter that looks like C is a different letter and stands for the s sound.

Which one should you use?

Be careful with music. In Russian note names си is the note B, while the note C is called до.

How does it change in a sentence?

Си does not change its ending, so it stays the same after prepositions, as in на Си.

How do you pronounce it?

It is pronounced like the English word see.

What mistakes should you avoid?

Do not use си for the note C in music, where Russian says до. For degrees Celsius Russian simply keeps the symbol °C.

Did you know?

  • In the context of the 'C' programming language, Russian speakers use the preposition на to say на Си, which literally translates to 'on C'.
