Judgment of French seen by native American (6)
I believe the answer is:
decree
'judgment' is the definition.
(I've seen this in another clue)
'of french seen by native american' is the wordplay.
'of french' becomes 'de' ('of' in French).
'seen by' means one lot of letters go next to another.
'native american' becomes 'cree' (an indigenous people of North America).
'de'+'cree'='DECREE'
(Other definitions for decree that I've seen before include "An official proclamation or ruling" , "Official edict" , "An official order or judgement" , "Recede (anag.)" , "Commandment" .)
