Put steps outside at home with men planning (9)
I believe the answer is:
ordinance
'planning' is the definition.
(I've seen this before)
'put steps outside at home with men' is the wordplay.
I cannot really understand how this works, but
'at' could be 'in' (synonymous in some cases - eg at school, in school) and 'in' is found in the answer.
'steps' could be 'dance' ('dance step' can be a synonym of 'step') and 'dance' is found in the remaining letters.
'men' could be 'or' (Other Ranks: non-commissioned soldiers) and 'or' is found in the answer.
No letters remain.
This may be the basis of the clue (or it may be nonsense).
Can you help me to learn more?
(Other definitions for ordinance that I've seen before include "Bill" , "Showing resolution" , "law" , "Authoritative decree" , "Rule" .)
