Behind given smack, producing sensation felt later (10)
I believe the answer is:
aftertaste
'sensation felt later' is the definition.
I can't judge whether this defines the answer.
'behind given smack' is the wordplay.
'behind' becomes 'after' (eg after or behind someone in a queue).
'given' is a charade indicator (letters next to each other).
'smack' becomes 'taste' (to smack of something is to taste of it).
'after'+'taste'='AFTERTASTE'
'producing' is the link.
Can you help me to learn more?
(Other definitions for aftertaste that I've seen before include "lingering flavour" , "Lingering sensation in mouth" , "Relish experienced" , "Consumer sensation" , "Residue on the palate" .)
