Konstantin
From Greek, the name carries the sense of "constant, steadfast". It clears the top thousand for boys in Poland, but only just: most Poles will go a lifetime without meeting one, and the few newborns each year are all boys.
Konstantin Pronunciation
Konstantin is pronounced kons-TAHN-teen (/kɔnsˈtantin/).
What Konstantin means
Where Konstantin comes from and what it has meant to the people who carry it.
Konstantin traces back to the Greek Konstantinos, a name built on the Latin adjective constans, meaning constant or steadfast. That root fixes the meaning before any story attaches to it.
The first Konstantin most people can name is Constantine the Great, the Roman emperor who moved his capital east and gave Constantinople its name. From there the name spread across the Orthodox world, which is why it reads as thoroughly Russian to many ears, though German parish records carry it too.
In Polish it settles into Konstanty, and among friends it shortens to Kostek. Short and quick. The formal version and the nickname sit far apart on a school register, one for the teacher who reads out Konstanty, one for the boys who shout Kostek.
A child given this name answers to steadiness spelled into it: stały, niezłomny. He may never think once about the Greek behind the sound. The meaning holds anyway, in the older Konstanty and the everyday Kostek alike.
