"Blend of Ke and Andrea"
The name Keandrea is commonly a female name.
Keandrea is a modern American formation rather than an inherited name. Its structure matches the Ke- element seen in American coinages such as Keisha and Keandra, joined to Andrea, and it first appears in United States birth records in 1983, long after Andrea was in established use.
The pronunciation of Keandrea is kee-AN-dree-uh.
