"Blend of La and Ronda"
The name Laronda is commonly a female name from the "American" origin.
Laronda is a twentieth-century American formation made from the La- prefix, which appears in many US girls' names of the same era such as Laverne and Latoya, attached to Ronda, a spelling of Rhonda. The name first appears in US birth records in 1952, which fits that pattern of formation rather than an inherited tradition. No meaning can be assigned beyond the elements it is built from.
The pronunciation of Laronda is luh-RON-duh.
