Day I wed, a dispute gradually subsided (4,4)
I believe the answer is:
died away
'gradually subsided' is the definition.
The answer and definition can be both related to change as well as being past participle verbs.
Maybe there's a link between them I don't understand?
'day i wed a dispute' is the wordplay.
'dispute' is an anagram indicator (I've seen 'disputed' mean this).
'day'+'i'+'wed'+'a'='dayiweda'
'dayiweda' with letters rearranged gives 'DIED AWAY'.
Can you help me to learn more?
(Another definition for died away that I've seen is " gradually disappeared".)
