Splinching

"Splinching, or the separation of random body parts, occurs when the mind is insufficiently determined. You must concentrate continually upon your destination, and move, without haste, but with deliberation…"

- Wilkie Twycross instructing his Apparition class in 1996

Known cases of splinching
Susan Bones splinched herself during her first Apparition lesson, losing a leg; it was reattached, but the incident left her shaken. It was said to be the first "exciting thing happening" during the lesson.

Ron Weasley failed his Apparition test due to leaving half of an eyebrow behind. Having left school in his Seventh year without ever having passed the test, he was badly injured after splinching away part of his upper arm while escaping from the Ministry of Magic in 1997. He was saved through the quick first-aid work of Hermione Granger, who applied Dittany to the wound. When he briefly abandoned Harry Potter and Hermione Granger, he also ended up losing a pair of fingernails.

Arthur Weasley told Harry, Ron and Hermione about two people who tried apparation without a licence and splinched themselves, leaving half of themselves behind.
