Unknown; possibly a modern elaboration of Nayeli or Nadia.
Naidely is a rare modern invention, likely created within Spanish-speaking communities in the United States. It may be a creative blend of names like Nayeli, meaning 'I love you' in Zapotec, or Nadia, meaning 'hope.' Because it is a contemporary coinage, it lacks a singular historical etymology.
