There are many closely-related definitions of reading, from a live performance like a poetry reading or a minister's Bible reading, to an individual interpretation of written material, like your feminist reading of classic fairy tales.

There are, in addition, several towns in the UK and the US called Reading, but those are usually pronounced redding.
