Amazement is what you feel when you're shocked or astonished by something. When you feel amazement, you can't quite believe what you're seeing or hearing.
To amaze someone is to shock, surprise, and astonish them. Amazement is the emotion produced by truly unusual and surprising things. A juggler throwing around fire can produce amazement. A child reciting thousands of digits of Pi will create amazement. Parents feel amazement at the birth of their children. This is a strong feeling resulting from incredible events. No one feels amazement about average, boring stuff.
