Landscape glimpsed reportedly (5)
I believe the answer is:
scene
'landscape' is the definition.
(I've seen this in another clue)
'glimpsed reportedly' is the wordplay.
'glimpsed' becomes 'seen' (I've seen this in another clue).
'reportedly' shows a homophone (sound like).
'seen' is a homophone of 'SCENE'.
(Other definitions for scene that I've seen before include "site" , "Landscape; public display of anger" , "Subdivision of a drama" , "Subdivision of act in play" , "Location; outburst" .)
