Melted away and perished, wrapping up a bit of witchcraft (9)
I believe the answer is:
dispelled
'melted away' is the definition.
Although both the answer and definition are past participle verbs, I cannot understand how one could define the other.
'perished wrapping up a bit of witchcraft' is the wordplay.
'perished' becomes 'died' ('die' can be a synonym of 'perish').
'wrapping up' means one lot of letters goes inside another.
'a bit of witchcraft' becomes 'spell' (I've seen this in another clue).
'died' enclosing 'spell' is 'DISPELLED'.
'and' acts as a link.
Can you help me to learn more?
(Another definition for dispelled that I've seen is " Piled sled (anag.)".)
