Took issue with smack (4)
I believe the answer is:
kiss
'smack' is the definition.
(thesaurus)
'took issue with' is the wordplay.
'with' indicates a hidden word.
'KISS' can be found hidden inside 'took issue'.
(Other definitions for kiss that I've seen before include "Osculate" , "Smooch" , "Cross" , "Affectionate greeting" , "Amorous greeting" .)
