Seen cry wildly — “That is beautiful to see” (7)
I believe the answer is:
scenery
'that is beautiful to see' is the definition.
(scenery can mean beautiful surroundings)
'seen cry wildly' is the wordplay.
'wildly' indicates anagramming the letters.
'seen'+'cry'='seencry'
'seencry' anagrammed gives 'SCENERY'.
(Other definitions for scenery that I've seen before include "flats" , "view in the country" , "Theatre stage feature" , "Items on stage" , "Theatrical background" .)
