Field found in a clearing (3)
I believe the answer is:
lea
'field' is the definition.
(thesaurus)
'in a clearing' is the wordplay.
'in' indicates the answer is hidden within the clue.
'LEA' can be found hidden inside 'clearing'.
'found' is the link.
(Other definitions for lea that I've seen before include "Poetically, a piece of meadow or pasture" , "Open pasture" , "Open grassy land; river" , "Open area of grassy or arable land" , "'The lowing herd wind slowly o'er the . . .'" .)
