Journey north with soldier reveals pattern (7)
I believe the answer is:
paragon
'pattern' is the definition.
(thesaurus)
'journey north with soldier' is the wordplay.
'journey' becomes 'go' (I've seen this in other clues).
'north' becomes 'n' ('N' can be a synonym of 'north').
'with' says to put letters next to each other.
'soldier' becomes 'para' (para is a kind of soldier**).
'go'+'n'='gon'
'gon' put after 'para' is 'PARAGON'.
'reveals' is the link.
(Other definitions for paragon that I've seen before include "Flawless model" , "A model as of virtue" , "A perfect person - pagan or what?" , "Perfect type" , "Model of conduct" .)
