Unknown; likely a modern invented name
Naelith is an extremely rare name with no established etymological history. It appears to be a modern creation, possibly blending the soft 'Nae' sound found in names like Maelys or Naelle with the 'lith' suffix seen in Lilith or Meredith. Because it lacks a historical root, its meaning is subjective and determined by the parents who choose it.
