"Blend of Cy and Leigh"
The name Cyleigh is commonly a female name from the "American" origin.
Cyleigh is a modern American formation that can be read as the element Cy, a short form of names such as Cyrus and Cyril, joined to Leigh, an English surname that is also used as a given name. The second element follows the -leigh spelling pattern that appears frequently in US girls' names coined from the 1990s onward, and Cyleigh itself first appears in US birth records in 1999. Both parts are established name elements, but the combination is recent rather than inherited from an older naming tradition.
The pronunciation of Cyleigh is SIGH-lee.
