Eowyn

Eowyn is the unaccented spelling of Éowyn, the name J. R. R. Tolkien created for a woman of Rohan in The Lord of the Rings. He used Old English elements for “horse” and “joy,” reflecting the language and horse-centered culture he associated with Rohan. The construction is not a Welsh name ending in wyn.

The character is the niece of King Théoden and a central figure in the battle against the Lord of the Nazgûl. That story gives the name a specific literary identity rather than a vague fantasy association. Éowyn preserves Tolkien's accent mark, while Eowyn is the form often entered without it. The literal components are clearer as “horse joy” than the looser interpretation “horse lover.”
