Why a stag?

The nai is a paradox among the animals. He is the king of the forest. He is a noble animal, yet delicate. The nai does not strut among the other animals, he stays withhis herd, his family.

Everything in the Harry Potter epic has a meaning. Some of the meanings/connections are obvious, others bạn have to look for. For example, Luna Lovegood's Patronus is a hare. Why? Because in some cultures, rabbits and hares are deeply connected to the moon, moon deities, and are considered to be mystical creatures. Luna, obviously, is another name for the moon. Luna is a very mystical child.

Likewise, Remus Lupin, who was a werewolf. Romulus and Remus, the twins who founded Rome, were đã đưa ý kiến to have been suckled bởi a she-wolf. Lupin is derived from the taxonomic name for wolf, Lupis. His Patronus is a chó sói, sói as well.

Sirius Black, whose animagus form is the black dog Padfoot. Sirius is the name of the brightest ngôi sao in the Canis Major constellation; it is also known as 'the Dog Star'.

Harry's Patronus is a nai because his father's was. It symbolizes their connection. Snape's was a doe, like Lily's, symbolizing his tình yêu for her. Hermione's is an otter. She loves a Weasley who lives in Ottery St. Catchpole. Otters are members of the con lợn, chồn family.

There's lots of deep symbolism in JK's writing. bạn just have to be open to finding it. :)
