Journey north to support soldier reveals pattern (7)
I believe the answer is:
paragon
'pattern' is the definition.
(thesaurus)
'journey north to support soldier' is the wordplay.
'journey' becomes 'go' (I've seen this in other clues).
'north' becomes 'n' ('N' can be a synonym of 'north').
'to support' means one lot of letters go next to another.
'soldier' becomes 'para' (para is a kind of soldier**).
'go'+'n'='gon'
'gon' put after 'para' is 'PARAGON'.
'reveals' acts as a link.
(Other definitions for paragon that I've seen before include "Very good example" , "Perfect example of a quality" , "Perfect embodiment of a concept" , "Perfect type" , "Flawless model" .)
