Meaning & origin
Cylus is a rare modern name that first appeared in U.S. records in 1997. Its popularity peaked in 2012, but since 2013 its use has been steadily falling, reflecting its status as an uncommon and relatively recent invention. With a current rank of 3,513 in 2025 and a 1-in-53,377 frequency, Cylus remains a distinctive choice. The name has not been recorded in any U.S. state's top baby names, suggesting its usage is scattered and extremely limited. Despite its obscurity, Cylus fits a pattern of modern names ending in '-us' that sound classical, like Silas or Cyrus, which may have inspired its coinage.
Cylus is a rare modern coinage, first recorded in the United States in 1997. It may have been formed as a variant of Silas (derived from the Latin Silvanus, meaning 'of the forest') or as a unique creation inspired by similar-sounding names like Cyrus. Its usage has remained extremely low, with no clear etymological tradition.
