What is a good witch school name?

JKR, 1999:
"""Q: How do you come up with names?
A: Some I make up. Some mean something. Dumbledore is olde English for bumblebee. I thought I made up Hogwarts, but recently a friend said, 'Remember we saw lilies in Kew gardens (a garden in London.)' Apparently there are lilies there called Hogwarts. I'd forgotten!"""
I believe a good name carries meaning to the author and is organic to the work's theme. So you have some educational institution for the thaumaturgically gifted, but what of it? Design the plot, develop a writing style, and then you (or a reviewer of your work) might have a better idea of what your preferences are.
