"Blend of La- and Kayla"
The name Lakayla is commonly a female name from the "American" origin.
Lakayla is a modern American formation that attaches the prefix La-, familiar from twentieth-century coinages such as Latoya and LaShawn, to the name Kayla. No use of the name is recorded before it appears in United States birth records in 1980, which fits that pattern rather than an older documented naming tradition.
The pronunciation of Lakayla is luh-KAY-luh.
