isolt

Isolt is a feminine given name, a variant spelling of Isolde (also Iseult), a name long associated with the Tristan and Isolde legend in medieval literature. The exact etymology is uncertain; Isolde is generally considered to be of Celtic origin, with multiple proposed meanings and no settled consensus. The form Isolt is used chiefly in English-speaking contexts and appears alongside Isolde, Iseult, and other variants.

The name has appeared in romance literature and historical writings for centuries. In Arthurian legend, Isolde is the princess whose love for Tristan becomes central to the narrative, often featuring a love potion and tragedy. The name’s associations with romance and tragedy have made it a persistent influence on Western naming.

In modern popular culture, Isolt Sayre is a character in the Wizarding World created by J. K. Rowling. She is described as a founder of Ilvermorny School of Witchcraft and Wizardry in North America, a backstory that expands the franchise’s American branch of magic. The Tristan and Isolde romance remains the most influential source of the name’s perception in literature, and Isolt continues to be used in contemporary naming for its antique and literary resonance.
