Management worry over difficulty losing leader (11)
I believe the answer is:
stewardship
'management' is the definition.
(I've seen this in another clue)
'worry over difficulty losing leader' is the wordplay.
'worry over' becomes 'stew' (I've seen this in another clue. I am not sure about the 'over' bit.).
'difficulty' becomes 'hardship' (hardship is a kind of difficulty).
'losing leader' means to remove the first letter.
'hardship' with its first letter taken away is 'ardship'.
'stew'+'ardship'='STEWARDSHIP'
Can you help me to learn more?
(Other definitions for stewardship that I've seen before include "Management of somebody else's property" , "Job for resigned MP" , "Management or care (of something)" , "Administration of property, finance etc" .)
