Field bluejay regularly missed (3)
I believe the answer is:
lea
'field' is the definition.
(lea can mean a meadow or field of grass)
'bluejay regularly missed' is the wordplay.
'regularly missed' means one should take alternating letters (letters removed at regular intervals).
The alternate letters of 'bluejay' are 'LEA'.
(Other definitions for lea that I've seen before include "area of grassland" , "'The lowing herd wind slowly o'er the . . .'" , "Land growing grass" , "Open country" , "Meadow (poetic)" .)
