Sylwiusz
From the Latin Silvius, "of the forest". Only about 300 men in Poland carry it and no boys were given it last year, so most Poles will never meet one.
Sylwiusz Pronunciation
Sylwiusz is pronounced SIHLV-yoosh (/ˈsɨlvjuʂ/).
What Sylwiusz means
Where Sylwiusz comes from and what it has meant to the people who carry it.
Sylwiusz reaches back to the Latin silva, the word for forest and woodland. From that root Roman families built the name Silvius, and later the Polish form Sylwiusz. The meaning stays plain across those centuries: of the forest, someone who lives among the trees.
The name has a close relative. Sylwia is its cross-gender partner, more common in Poland today and drawn from the same Latin ground. Where Sylwia turns up often on a school register, Sylwiusz stays rarer, a fuller and older-sounding version of the same idea.
In Roman legend, Silvius was a king of Alba Longa, said to have been born in the woods, and that story gave the woodland sense a face. A boy named Sylwiusz carries that Latin silva forward, still meaning of the forest.
When Sylwiusz celebrates name day
Sylwiusz appears 2 times in the Polish name day calendar, never as a main name. The first of these dates is 31 May.
Rarer dates. Only the most complete calendars add this name on these days. Most skip them, so hardly anyone celebrates then.
