Unknown; likely a modern American blend
Chenise is a modern American invention, likely created in the late 20th century. It is often interpreted as a blend of the prefix 'Che-' with the name Denise, or a variation of the French-inspired name Shanice. Because it is a contemporary coinage, it lacks a traditional etymological root or historical meaning.
