amaze: [OE] Old English āmasian meant ‘stupefy’ or ‘stun’, with perhaps some reminiscences of an original sense ‘stun by hitting on the head’ still adhering to it. Some apparently related forms in Scandinavian languages, such as Swedish masa ‘be sluggish’ and Norwegian dialect masast ‘become unconscious’, suggest that it may originally have been borrowed from Old Norse.
The modern sense ‘astonish’ did not develop until the end of the 16th century; Shakespeare was one of its earliest exponents: ‘Crystal eyes, whose full perfection all the world amazes’, Venus and Adonis 1592. By the end of the 13th century both the verb and its related noun had developed a form without the initial a-, and in the late 14th century the word – maze – had begun to be applied to a deliberately confusing structure. => maze
