Dessert wine that may cause rumbling down below later (10)
I believe the answer is:
aftershock
'dessert wine that may cause rumbling down below later' is the definition.
Although both the answer and definition are singular nouns, I cannot understand how one could define the other.
'dessert wine' is the wordplay.
'dessert' becomes 'afters' (afters can mean a dessert course).
'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 "that causes another little wobble" , "another shake" , "Secondary earth tremor" , "Ground-breaking" , "What might have cracked open house" .)
