Jet on a hill, female takes over from man (8)
I believe the answer is:
fountain
'jet' is the definition.
(synonyms)
'a hill female takes over from man' is the wordplay.
I cannot quite see how this works, but
'a' is present in the answer.
'female' could be 'f' (common abbreviation) and 'f' is found within the answer.
'over' could be 'o' (cricket abbreviation) and 'o' is found in the answer.
'from' could be 'in' (I've seen this in other clues) and 'in' is located in the answer.
'man' could be 'n' (knight, a man in chess) and 'n' is present in the answer.
The remaining letters 'ut' is a valid word which might be clued in a way I don't see.
This may be the basis of clue (or it may be nonsense).
'on' acts as a link.
(Other definitions for fountain that I've seen before include "Artificial jet of water" , "Whence jets are sent up" , "Origin" , "Give out" , "Man-made jet of water" .)
