IPA: //zɑr//
KK: /tsɑr/
A title used for a Russian emperor or monarch, similar to a king.
The tsar ruled over Russia for many years before the revolution.
Tsar originates from the Latin word 'Caesar' (meaning emperor), which was used in the Byzantine Empire to denote a ruler. The term was later adopted into Slavic languages, particularly Russian, to refer to a monarch or emperor.
Think of the word 'Caesar' as a title for an emperor, which helps you remember that 'tsar' also means a ruler or monarch.
