What Bolesław means

Where Bolesław comes from and what it has meant to the people who carry it.

Bolesław comes from Slavic roots. The first part, bole, means "great" or "more"; the second, sław, means "glory." Put them together and you get wielka sława, great glory.

The name belonged to kings. Bolesław Chrobry, Bolesław the Brave, was crowned the first king of Poland in 1025, and later rulers took the same name after him. A boy called Bolesław grew up sharing his name with the men who built the early Polish state.

Everyday speech softens it. The diminutive is Bolek, the form a brother or a classmate would use. The cross-gender Bolesława hands the same glory to a daughter.

In the nineteenth century the writer Aleksander Głowacki chose Bolesław Prus as his pen name, and it is under that borrowed first name that his novels are still read. Call the roll in a Polish class today and you may still hear Bolek answer to great glory.
