Emotional shock of a revolution (4)
I believe the answer is:
turn
This could be a double definition.
'emotional shock' is the first definition.
'turn' can be an answer for 'shock' (I've seen this in other clues). I am unsure of the 'emotional' bit.
'a revolution' is the second definition.
(I've seen this before)
'of' acts as a link.
Can you help me to learn more?
(Other definitions for turn that I've seen before include "Change direction" , "Move in a new direction" , "Shock - move - change course" , "Swing round" , "(Of tide) change from flood to ebb" .)
