iseult

Etymology

Old French, the name of the queen who fell in love with Tristan in medieval romance Tristan and Iseult, perhaps from Celtic, of uncertain meaning, possibly Proto-Brythonic *Adsiltia (“she who is gazed upon”); compare Welsh syllu and Irish súil. Otherwise from Germanic, equivalent to Old High German is (“ice”) + hiltja (“battle”) (from Proto-West Germanic *hildi).
