What Sylweriusz means
Where Sylweriusz comes from and what it has meant to the people who carry it.
Sylweriusz comes from Latin. Behind it stands silva, the word for forest, and the name began life as a Roman cognomen, a byname that set a family among the trees. Its Polish sense is plain: leśny, z lasu, of the forest.
The same root fed Silvanus, the old Roman god of woodland and field, and it survives in cousins across Europe: Silverius in Latin, Silvère in French, Silverio in Italian.
The name's most famous bearer wore the papal crown. Silverius held the see of Rome from 536 to 537, was pushed aside in favor of Vigilius, and died soon after in exile. His reign was short. The Church keeps his memory on 20 June, and that date fixes the imieniny of every Polish Sylweriusz.

Sylweriusz appears 2 times in the Polish name day calendar, never as a main name. The first of these dates is 20 June.
