The name Merlin comes from ancient Celtic tradition and is connected to the legendary wizard-advisor of King Arthur, known for his wisdom and magic.

In Old Celtic, the name means “wonder” or “rough sea.”

Merlin is derived from the Welsh word Myrddin, which means “sea fortress” or “fort by the sea” and refers to the Welsh town of Carmarthen.

Myrddin was also the name of a 6th-century Welsh bard and prophet.

The name is also sometimes interpreted in French as “falcon” or as “hill by the sea.”
