"Blend of La and Shayla"
The name Lashayla is commonly a female name from the "American" origin.
Lashayla reads as a modern American formation: the initial La- element seen in twentieth-century American names such as Latoya and LaShawn, attached to Shayla, a name recorded in the United States from the mid-twentieth century. The spelling first appears in US birth records in 1977, which fits a recent American construction rather than an older inherited name. No earlier source in another language is documented for this spelling.
The pronunciation of Lashayla is luh-SHAY-luh.
