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 quite understand how this works, but
'at' could be 'in' (synonymous in some cases - eg at school, in school) and 'in' is located in the answer.
'steps' could be 'dance' ('dance step' can be a synonym of 'step') and 'dance' is found in the leftover letters.
'men' could be 'or' (military abbreviation for Other Ranks) and 'or' is present in the answer.
This accounts for all the letters.
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" .)
