Gromisław
Built from the old Slavic grom, "thunder", and sław, "glory", the same ending that closes Bolesław and Mirosław. Most Poles have never met one: it surfaced again only last year, and every bearer is male.
Gromisław Pronunciation
Gromisław is pronounced gro-MEES-wahf (/grɔˈmiswaf/).
What Gromisław means
Where Gromisław comes from and what it has meant to the people who carry it.
Gromisław breaks into two old Slavic parts. Grom means thunder. Sław means glory or renown, the same ending found in Bolesław and Mirosław. Together they give thunder and glory, or in Polish nieodparta sława, a fame that nothing turns back.
The first part carries more than weather. In older Polish `gromić` meant to strike down or rout an enemy, hard as a thunderclap. A Gromisław was framed as a man who wins loudly and is known for it. The record backs the reading. Dictionaries trace the name to the staropolskie stock and gloss it as one whose renown cannot be resisted.
Read down a Polish class register and the name stands apart from the Kacpers and Szymons around it. It is long, formal, plainly medieval.
Gromisław keeps two name-days, 25 February and 11 October.
