Connect good man with halo? (6)
I believe the answer is:
string
'connect' is the definition.
(thesaurus)
'good man with halo?' is the wordplay.
'good man' becomes 'st'.
'with' says to put letters next to each other.
'halo?' becomes 'ring' ('ring' can be a synonym of 'halo').
'st'+'ring'='STRING'
(Other definitions for string that I've seen before include "light cord" , "tier" , "Group of horses" , "train" , "Part of racket" .)
