Narrissa is probably a variant of Nerissa or Narissa, linked to a Greek word for the sea. That gives it a literary and maritime resonance, with a softer, more romantic atmosphere.
Narrissa feels elegant and flowing, with a name-shape that sounds both fanciful and refined. It belongs to the tradition of names that feel classical even when their exact history is a little diffuse. The sea association adds movement, depth, and a faintly poetic character.
