As J.R.R. Tolkien wrote in Tree and Leaf, "It was in fairy tales that I first divined the potency of the words, and the wonder of the things, such as stone, and wood, and iron; tree and grass; house and fire; bread and wine."
What words in the fairy tales do you find potent? An odd pairing of words might prompt you to see something in a different way. For example, a "glass slipper" is very strange. So is a "stone boat" or a "speaking horse."
What words have stopped you as you've read through a story? What are you prompted to wonder about?
Play with the words. Explore their roots. Openly ask your questions and see what answers come to you, and from whom.
