Deity gets a kiss on the chest (6)
I believe the answer is:
thorax
'chest' is the definition.
(synonyms)
'deity gets a kiss on' is the wordplay.
'deity' becomes 'thor' (Thor is an example).
'gets' is a charade indicator (letters next to each other).
'kiss' becomes 'x' (X can represent a kiss).
'on' says to put letters next to each other.
'thor'+'a'+'x'='THORAX'
'the' is the link.
(Other definitions for thorax that I've seen before include "Upper part of body" , "Part of the body containing 3" , "Some soldier perhaps" , "Trunk between neck and abdomen" , "Middle section of an insect" .)
