Vasilike is of Greek origin and means 'royal' or 'of the king'. It is a feminine name, derived from the Greek word 'vasileos', which translates to 'king'. Vasilike was quite popular in Greece during the late 19th and early-to-mid 20th centuries, but its usage has since declined. The name Vasilike has not gained significant international recognition, remaining largely a regional name within the Greek-speaking world. It is often shortened to Vaso or Vasia for informal use.
"Vasilike saw a notable increase in popularity from 1920 to 1969, with birth occurrences peaking at 8 during the latter year. However, this growth was not sustained into the following decade, as births once again decreased to 5 in 1973."
