"Blend of La and Vontae"
The name Lavontae is commonly a male name.
Lavontae is a modern American formation built from the La- prefix found in names such as LaToya and LaShawn, attached to Vontae, a given name attested in the United States in the same period. It first appears in US birth records in 1991, which is consistent with a late twentieth-century coinage rather than an inherited name. A related spelling, Lavonte, also appears in the records, so the name may alternatively be read as a respelling of that form.
The pronunciation of Lavontae is luh-VAHN-tay.
