Morgan

Possibly “sea circle”; the full meaning is uncertain.

Morgan comes from the old Welsh name Morcant or Morgant. Its meaning is uncertain, although “sea” and “circle” are a proposed combination. The Welsh tradition is masculine; in English, Morgan is used for women and men. Morgan le Fay brings an Arthurian association, though her name has a different textual history from Morcant. That literary layer can be part of the name’s appeal without fixing its meaning. In English /ˈmɔɹ.ɡən/, the first syllable carries the stress. The g gives the middle firmness, while m and n lend resonance. Morgan can feel substantial and quietly bold, with a compact rhythm that suits its old Welsh roots.

Etymology: Morgan continues Old Welsh Morcant or Morgant. One proposed analysis joins words for “sea” and “circle”, but its etymology is unresolved.
