Gets rid of wretched spiels after reread in the end (7)
I believe the answer is:
dispels
'gets rid of' is the definition.
Although both the answer and definition are verbs in their -s form, I cannot see how one could define the other.
'wretched spiels after reread in the end' is the wordplay.
'wretched' indicates anagramming the letters.
'after' is a charade indicator (letters next to each other).
'in the end' suggests the final letters.
The final letter of 'reread' is 'd'.
'spiels' is an anagram of 'ispels'.
'ispels' put after 'd' is 'DISPELS'.
Can you help me to learn more?
(Other definitions for dispels that I've seen before include "'Makes disappear, a doubt say (7)'" , "Scatters, drives away" .)
