Large leaf taken from soil often flipped over (5)
I believe the answer is:
folio
'large leaf' is the definition.
(large sheet of paper - leaf can mean a sheet)
'soil often flipped over' is the wordplay.
'over' indicates the answer is hidden within the clue (the clue contains or goes 'over' the answer).
'flipped' is a reversal indicator.
'oilof' can be found hidden inside 'soil often'.
'oilof' in reverse letter order is 'FOLIO'.
'taken from' is the link.
(Other definitions for folio that I've seen before include "eaf" , "Folded sheet - or book made from such" , "large book" , "Book; wrapper for loose papers" , "Leaf of paper" .)
