brusler

An obsolete pre-modern spelling of brûler (to burn), using the old 's' before a consonant to mark a long vowel — the same convention that turned isle into île and forest into forêt once the circumflex replaced the silent s in the 18th century. Never used in contemporary French outside quoted historical texts.

• Le vieux texte disait : « le feu brusloit dans l'âtre ». — The old text read: "the fire was burning in the hearth."
• On trouve « brusler » dans les écrits du XVIe siècle. — You'll find "brusler" in 16th-century writings.
• Cette orthographe a disparu avec la réforme de l'accent circonflexe. — This spelling disappeared with the circumflex reform.

Brusler isn't a variant to use in modern writing at all (unlike bruler, the still-current 1990 reform spelling) — it's purely historical and only appears when quoting or discussing old texts.
