Shock of orchard essentially disappearing in morning mist (5)
I believe the answer is:
amaze
'shock of orchard' is the definition.
'amaze' can be an answer for 'shock' (I've seen this before). I am unsure of the 'of orchard' bit.
'essentially disappearing in morning mist' is the wordplay.
'essentially' means to look at the middle letters.
'disappearing' becomes 'takingapowder' (taking a powder is a kind of disappearing).
'in morning mist' becomes 'maze' (I am not sure about this - if you are sure you should believe this answer much more).
The middle of 'takingapowder' is 'a'.
'a'+'maze'='AMAZE'
Can you help me to learn more?
(Other definitions for amaze that I've seen before include "Flabbergast" , "shock" , "Confound with wonder" , "Greatly surprise, astound" , "Affect with wonder" .)
