Suffering can lead to glorious work of art (8)
I believe the answer is:
painting
'work of art' is the definition.
(type of artwork)
'suffering can lead to glorious' is the wordplay.
'suffering' becomes 'pain' (I've seen this before).
'can lead to' says to put letters next to each other.
'glorious' becomes 'ting' (I can't justify this - if you can you should believe this answer much more).
'pain'+'ting'='PAINTING'
Can you help me to learn more?
(Other definitions for painting that I've seen before include "Artistic work" , "picture" , "Artistic composition" , "Artwork" , "Work of a kind" .)
