Amaze: The etymology of the word is both obvious and surprising, it does in fact, mean ‘A maze’.
It is derived from the Middle English (c. 1150 CE to c. 1470 CE) word ‘amased’. Which is in turn derived from the Old English (pre 1150 CE) word ‘amasod’. Both words meaning, as amazed does today, to surprise or confuse.
This in turn is a combination of the words ‘a’ and ‘mæs’ which became the modern ‘maze’, this makes sense as mazes are traditionally confusing and contain surprises. The word has been used as a simile to describe situations which have a maze like an effect.
