Upside-down person in bondage secured by that woman's brace (7)
I believe the answer is:
refresh
'brace' is the definition.
(I've seen this before)
'upside-down person in bondage secured by that woman's' is the wordplay.
'upside down' shows that the letters should be reversed in order.
'person in bondage' becomes 'serf' (I can't explain this - if you can you should believe this answer much more).
'secured by' is an insertion indicator (inserted letters are held or secured).
'that woman' becomes 'her' ('her' refers to a woman).
'serf' going into 'her' is 'hserfer'.
'hserfer' written backwards gives 'REFRESH'.
Can you help me to learn more?
(Other definitions for refresh that I've seen before include "Invigorate -- her serf (anag)" , "Restore strength and vigour as with food and drink" , "Renew" , "Give new energy to" , "Revive, cheer" .)
