Merlin: Baby Name Meaning, Nicknames and Numerology

What does the baby name “Merlin” mean?

Merlin is a name steeped in Arthurian legend, believed to derive from ancient Celtic roots meaning sea fortress, and forever linked to the most famous wizard in Western mythology.

Origin of the baby name Merlin

Merlin comes from the Latinized form Merlinus, which was itself adapted from the Old French rendering of the Welsh name Myrddin. The Welsh name is thought to derive from Proto-Celtic elements: "mori" meaning sea and "dunom" meaning fort or fortified settlement, giving Merlin a grounded ancient meaning of something like sea fortress. The Latin form Merlinus was popularized by Geoffrey of Monmouth in his 12th-century chronicles of the British kings.
