{{Muggles' Guide to Harry Potter/Beginner Spoiler}}
[[Muggles' Guide to Harry Potter/Characters/Harry Potter|Harry]] learns this spell from [[Muggles' Guide to Harry Potter/Characters/Remus Lupin|Remus Lupin]] in [[Muggles' Guide to Harry Potter/Books/Prisoner of Azkaban/Chapter 12|''Harry Potter and the Prisoner of Azkaban'']]. Harry's ability to cast a corporeal Patronus in his third year of magical studies shows his ability as a wizard, as it is a very advanced spell which is thought to be too difficult for underage wizards, in fact the vast majority of witches and wizards are unable to produce any form of Patronus. In his fifth year, when Harry takes his [[Muggles' Guide to Harry Potter/Major Events/OWL exams|OWLs]], his [[Muggles' Guide to Harry Potter/Magic/Charms|Charms]] examiner offers him an extra point if he can produce a corporeal Patronus. A point, or a letter grade, would be worth about 15% of his total marks, so achieving this one charm is seen as quite valuable.
The primary purpose of the Patronus, as mentioned, is as defence against Dementors. Professor Lupin describes it thus: "... a kind of anti-Dementor – a guardian which acts as a shield between you and the Dementor." And: "The Patronus is a kind of positive force, a projection of the very things that the Dementor feeds upon – hope, happiness, the desire to survive – but it cannot feel despair, as real humans can, so Dementors can't hurt it." Presumably, the Dementor, finding that the being confronting it does not suffer as a human would, retreats in confusion. In [[Muggles' Guide to Harry Potter/Books/Order of the Phoenix/Chapter 1|''Harry Potter and the Order of the Phoenix'']] we see Harry's Patronus charge at the Dementors; though the Patronus may have no physical body, the Dementor, being sightless, cannot see that, all it can sense is this emotional blast furnace, which is charging at it, and it will retreat to save itself.
