Wart

"[Ron] had just made Harry feel rather better by telling him how he had told the examiner in detail about the ugly man with a wart on his nose in his crystal ball, only to look up and realize he had been describing his examiner's reflection."

- Description.

A wart is a small, rough growth resembling a cauliflower or a solid blister. They typically disappear after a few months but can last for years and can recur.

It is a popular historical theory that location and name of Hogwarts School of Witchcraft and Wizardry were both chosen by Rowena Ravenclaw, who dreamed that a warty hog was leading her to the cliff by the lake.

Delfina Crimp, one of London's most popular clothiers in the 15th century, had a large wart on her chin which popped out of her face to reveal her hidden wand.

A wizard by the name of Warty Harris used to own some toads. Whether he actually had warts or the sobriquet was due to the belief that toads cause warts is unknown.

By the mid-1990s, the Daily Prophet ran a segment called "Arts & Warts", on page eleven. On Christmas, 1991, Harry Potter got a Grow-Your-Own-Warts kit from a Christmas cracker, but but there is no evidence that he ever used it. The warts of a Giant Purple Toad have magical properties, and can be used in combination with Peacock feathers and Eagle Owl feathers to produce a Dragon Tonic.

The examiner who tested Ronald Weasley in his practical Divination O.W.L. had a wart on his nose.
