Is the girl with wings in Coraline a fairy?

Answer 1

Yes. She is described as being clothed in odd, shimmering material (like cobwebs), wears a small silver circlet and is a somewhat smallish person.

Later, when Coraline meets all the ghost children in her dream, this same child is said to have insect like wings, and flies when the other children have to walk. She also happily eats a bowl of honeysuckle flowers when everyone else has ice cream.

Coupled with the fact that she is the oldest ghost there, and has the most archaic speech patterns, we can also assume that she truly is a fairie...the first type of being stolen away by the Beldam/Other Mother and from a time when fairie kind still lived and flourished outside of dreams.
