Wasil, derived from the Slavic 'Wacław', is a unique and distinctive name of Polish origin. Its popularity has been predominantly limited to Eastern European countries, particularly Poland, where it has been traditionally used for generations. The name Wasil has no specific meaning associated with it, but rather holds cultural significance as a historically popular choice among Polish families.
"Wasil was quite popular for a brief period around World War I, with a notable peak in popularity in 1918. However, it appears the name's appeal waned thereafter, as there were fewer than 10 births each year from 1920 onwards."
