Sweet wine that might shake you up (10)
I believe the answer is:
aftershock
'sweet wine that might shake you up' is the definition.
Although both the answer and definition are singular nouns, I cannot understand how one could define the other.
'sweet wine' is the wordplay.
'sweet' becomes 'afters' (I've seen this before).
'wine' becomes 'hock' (hock is a kind of wine).
'afters'+'hock'='AFTERSHOCK'
Can you help me to learn more?
(Other definitions for aftershock that I've seen before include "Tremor following earthquake" , "Ground-breaking" , "no great shakes" , "gives one the shakes later" , "that causes another little wobble" .)
