WAGs perhaps quickly run setter over (6)
I believe the answer is:
hareem
'wags perhaps quickly' is the definition.
I can't judge whether this definition defines the answer.
'run setter over' is the wordplay.
'run' becomes 'hare' (hare can mean to run very fast).
'setter' becomes 'me' (the setter of the clue).
'over' shows that the letters should be reversed in order.
'me' backwards is 'em'.
'hare'+'em'='HAREEM'
Can you help me to learn more?
(Other definitions for hareem that I've seen before include "Muslim living quarters for women" , "Group of women" , "Living quarters for wives and concubines" .)
