A doe, same as Lily Evans because he loved her so much.
According to the character Remus Lupin, a witch or wizard's Patronus can change from a "great shock" or "emotional upheaval" (Harry Potter and the Half-Blood Prince, USA Scholastic hardcover edition, p340). Snape's Patronus may have changed because he was tormented by her death or it may always have been a Doe as he always loved her.
In the chapter "The Prince's Tale," in Harry Potter and the Deathly Hallows, Snape casts his doe Patronus in front of Dumbledore, 16 years after Lily's death. Dumbledore asks him, "After all this time?" and Snape replies, "Always." (Harry Potter and the Deathly Hallows, USA Scholastic hardcover edition, p687).
Nymphadora Tonks patronus takes the shape of a werewolf.
since severus snape had a doe patronus and he wasn't a marauder, then he has no nickname on the marauders map. however, the marauders did have a nickname for snape being snivellus as a mickey take on his name severus.
Harry Potter's patronus takes the shape of a stag, the animagus and patronus form of his father. The Patronus spell is used against Dementors but can also be used as a method of communication.
It is a doe because Snape always loved Harry's mother, Lily, and her patronus was a doe. His never changed as he always loved her, as shown in the final book. Lily's patronus is a doe as it is complimentary to James Potter's stag.
Remus Lupin's patronus is a wolf, a regular wolf not a werewolf. He rarely cast a corporeal patronus, preferring instead just to produce a wisp of smoke, as he felt it gave too much away about him.
Rowling has never stated what Stan's patronus is. In fact, it's unclear whether he even can produce a patronus. Death Eaters, with the exception of Snape since he stopped being a Death Eater, are unable to produce a patronus. Most fans believe that, since Stan was simply Imperiused and was not a true Death Eater, that Stan was indeed able to produce a patronus.
It is a silver doe, like Lily Potter's because he loved her all his life.
Each person who casts a fully formed patronus will have a different one which will take the shape of an animal. The animal will be silver.
It was first in the lake, and later in the Gringotts.The goblin did take it, but it was still magically bound to the Sorting Hat, so the Hat could give it to Neville.
There are three quizzes you can take on Pottermore. The first is the Sorting Hat quiz, which tells you which house you are in (I'm a Hufflepuff), the Wand quiz, which tells you what wand chooses you (haven't taken), and the Patronus quiz, which tells you what your Patronus is.
A stag.
Although Lily despised the path Severus decided to take, she loved him as a person and as a friend. There were many others, such as Harry, who never really loved Severus, but grew to respect him when they found out the entire truth to his story.View the Discussion Page below for more.
