Fierce woman set fee out for delay (4,4,4)
I believe the answer is:
drag ones feet
'delay' is the definition.
(dragging one's feet is a kind of delaying)
'fierce woman set fee out' is the wordplay.
'fierce woman' becomes 'dragon' (I've seen this before).
'out' indicates an anagram (out can mean wrong or inaccurate).
'set'+'fee'='setfee'
'setfee' is an anagram of 'esfeet'.
'dragon'+'esfeet'='DRAG ONES FEET'
'for' is the link.
(Other definitions for drag ones feet that I've seen before include "Be reluctant" , "Hang back" , "Act with reluctance" , "Be deliberately slow to act" , "Slug" .)
