Terrible scene, woven on goddam weaving device (4,3,5)
I believe the answer is:
doom and gloom
'terrible scene woven' is the definition.
I know nothing about this answer so I can't judge whether it can be defined by this definition.
'on goddam weaving device' is the wordplay.
'weaving' indicates anagramming the letters (letters weaved together differently).
'device' becomes 'loom' (loom is a kind of device).
'on'+'goddam'='ongoddam'
'ongoddam' is an anagram of 'doomandg'.
'doomandg'+'loom'='DOOM AND GLOOM'
Can you help me to learn more?
(Other definitions for doom and gloom that I've seen before include "Miserable prospect (often spread)" , "State of general depression" , "Bleak outlook" , "Pessimists' prognostication" .)
