Area of clear pasturage (3)

I believe the answer is:
lea
'pasturage' is the definition.
(I've seen this in another clue)
'area of clear' is the wordplay.
'area of' indicates the answer is hidden within the clue (I've seen this in other clues).
'LEA' is hidden within 'clear'.
(Other definitions for lea that I've seen before include "area of grassland" , "Field" , "Meadow (poetic)" , "Grass area" , "'The lowing herd wind slowly o'er the . . .'" .)
