In the fifth grade, Harry Potter mainly studied potions, what he learned in the metamorphosis class (what becomes what), and the names of some spells.

Transfiguration is the magic of changing one object into another. It can turn inanimate objects into living things, and vice versa. Some deformation spells can change a certain part of things, for example, a person's ear can become a rabbit's ear. At Hogwarts School of Wizardry, Metamorphosis is taught by Professor McGonagall. Fifty years ago, Dumbledore was a perverted teacher at Hogwarts (the Chamber of Secrets). The transfiguration spell has been used in ancient times. Circe, a witch who lives on the Greek island of Ayu, is famous for turning a lost sailor into a pig (Chamber of Secrets/Games).

Contrary to deformation, deformation can change the deformed object back to its original shape.

Transfiguration spells don't need much magic.

The transformation spell is a famous spell in the Harry Potter series, and its specific spell will change according to the changing things. The more difficult the deformation is, the greater the force is needed. If a match is turned into a needle, only a small force is needed. But if you turn a person into an animal, the magic power needed is extremely powerful.

A professor who wants to take Metamorphosis class can copy it, because I am also a professor of Metamorphosis class (Muggle things are quite useful, whisper bb).
