How many characters are there in Harry Potter and the Stone?

It's impossible to give an exact number of characters in "Harry Potter and the Philosopher's Stone" (the original British title) without a very specific definition of what counts as a character.

Here's why:

* Named vs. Unnamed: Do we count only characters with names? What about minor characters mentioned only once?

* Speaking vs. Non-Speaking: Do we count characters who only appear in the background or have no dialogue?

* Living vs. Non-Living: Do we count magical creatures like Fluffy or the ghosts?

However, we can say that the book features a large cast of characters. Some of the major ones include:

* Harry Potter

* Ron Weasley

* Hermione Granger

* Albus Dumbledore

* Severus Snape

* Rubeus Hagrid

* Draco Malfoy

* Professor McGonagall

It's a good exercise to go through the book and count the characters that are important to the story. This will give you a better idea of the scope of the book's world.
