Removed unedifying section over strip (6)
I believe the answer is:
denude
'strip' is the definition.
(I know that strip can be written as denude)
'removed unedifying section over' is the wordplay.
'section' indicates a hidden word.
'over' shows that the letters should be reversed in order.
'eduned' is hidden within 'removed unedifying'.
'eduned' reversed gives 'DENUDE'.
(Other definitions for denude that I've seen before include "Lay bare" , "Strip away cover, make bare" , "Strip cover from, as leaves from trees" , "Strip - expose" , "Put off covering" .)
