Savour a kiss (5)
I believe the answer is:
smack
I believe this clue is a double definition.
'savour' is the first definition.
(synonyms)
'a kiss' is the second definition.
(smack is a kind of kiss)
(Other definitions for smack that I've seen before include "Hit with an open hand" , "Slap the fishing vessel" , "Sharp taste" , "box" , "Hit - fishing vessel" .)
