Meaning & origin

Cylis first appeared in U.S. birth records in 1999, placing it among the modern wave of invented names that blend familiar sounds with distinctive spelling. Its popularity peaked in 2013, but since 2012 its trajectory has been falling, making it an even rarer choice in the 2020s. With a rank of 5,861 and a 1-in-113,872 incidence, it remains a highly uncommon name. No top states have recorded significant use, suggesting it is scattered thinly across the country. Parents drawn to Cylis likely appreciate its similarity to established names like Silas while preferring a more unique, contemporary look.

Cylis first appeared in U.S. birth records in 1999, suggesting a modern coinage. It may be a creative respelling of the Greek name Silas (from Latin Silvanus, meaning 'of the forest') or a variant of the Latin name Caelius ('heaven'), but no direct etymological link has been established. Its usage has remained rare, peaking in 2013.
