Unknown; possibly a modern American creation
Nashay is a modern American name with no clear etymological root. It is likely a creative combination of the popular 'Na-' prefix with the name Shay, or a phonetic variation of names like Na'shae. Because it lacks a traditional history, its meaning is often interpreted by parents as unique or individualistic.
