What Caspian Means
Caspian refers to the great inland sea and the people it's named for. The Caspii name is sometimes said to mean white, but etymologists have not confirmed it, so the name's sense is mainly geographical.
Where Caspian Comes From
Classical writers knew the Caspii, a people living on the southwestern shores of the sea, and Greek and Latin named the water after them, as Caspium mare. Modern reference sites repeat a suggestion that the name meant white, though The Bump notes it's unconfirmed. Lewis chose Caspian for a young king in his 1951 novel Prince Caspian, and the character returns in The Voyage of the Dawn Treader. Earlier use as a first name is almost unknown, so this is close to a literary creation.
