After a bad start, wish aloud to end the pain! (7)
I believe the answer is:
anguish
'the pain' is the definition.
(anguish is a kind of pain)
'after a bad start wish aloud to end' is the wordplay.
I cannot quite understand how this works, but
'a' could be 'an' and 'an' is present in the answer.
This may be the basis of clue (or it may be nonsense).
Can you help me to learn more?
(Other definitions for anguish that I've seen before include "Hi, Angus - that hurts" , "Heartache, great distress" , "Great sorrow" , "Extreme mental distress" , "Extreme misery" .)
