Cylus is a unique and distinctive given name of unknown etymology, suggesting it may be of modern coinage. The name consists of three letters: 'C', 'y', and 'lus'. Its pronunciation is believed to follow the standard English sounds for these letters, /ˈsaɪləs/. Cylus is not derived from any known Latin or Greek names, nor does it have a clear connection to other languages. As such, its meaning and origin remain elusive.
"Cylus experienced a significant surge in popularity between 2007 and 2012, with a peak of 77 births in 2012. However, it has since seen a decline, with only 36 births recorded in 2022."
