Region Myanmar easily covers (4)
I believe the answer is:
area
'region' is the definition.
(I know that region can be written as area)
'myanmar easily covers' is the wordplay.
'covers' says the answer is hidden in the clue (I've seen 'covering' mean this).
'AREA' can be found hidden inside 'myanmar easily'.
(Other definitions for area that I've seen before include "'Tract, region (4)'" , "Locality" , "Field -- expanse" , "Region; extent of a surface" , "Space for a specific purpose, say picnic" .)
