An alumna of Beauxbatons Academy in France, Fleur is a talented witch, powerful enough to be selected as a champion in the prestigious Triwizard Tournament. After studying with Bill, she now speaks fluent English, albeit with a strong French accent, whereas before she often had trouble expressing herself in her new language.
Her stunningly beautiful looks are in stark contrast (or perhaps in direct relation) to her often arrogant and snooty attitude. Her mannerisms so infuriate some of her fiance's family that an in-joke among their younger members is to refer to Fleur as 'Phlegm'; still, she is rarely rude or aggressive toward those with whom she is in direct contact.
Fleur has a younger sister Gabrielle, (born c 1987). Their grandmother was a veela, making them both at least one quarter veela. This heritage accounts for Fleur's fair hair, skin and eyes, and apparently her ability to entrance men. This could put her in danger from Voldemort and his followers, as they have a strong prejudice against "half-breeds." She is engaged to Bill Weasley, the eldest brother of Ron Weasley.
Fleur's wand is nine and a half inches, inflexible, made of rosewood and contains one of her Veela grandmother's hairs.
According to JK Rowling, her name comes from the French phrase fleur de la cour, meaning "flower of the court" or "noblewoman".
