Commanding soldiers from French camp (8)
I believe the answer is:
ordering
'commanding' is the definition.
(I've seen this before)
'soldiers from french camp' is the wordplay.
'soldiers' becomes 'OR' (military abbreviation for other ranks).
'from french' becomes 'de' ('from' in French).
'camp' becomes 'ring' (I am not sure about this - if you are sure you should believe this answer much more).
'or'+'de'+'ring'='ORDERING'
Can you help me to learn more?
(Other definitions for ordering that I've seen before include "Issuing instructions" , "Giving an instruction" , "Requesting (something) to be supplied" , "procurement" , "Instructing" .)
