Much worse though, resolved to give up (8)
I believe the answer is:
forswear
'give up' is the definition.
(I've seen this before)
'much worse though resolved' is the wordplay.
I cannot quite see how this works, but
an anagram of 'worse' is 'orswe' which is present in the answer.
'much' could be 'far' (I've seen this in other clues) and 'far' is present in the leftover letters.
No letters remain.
This explanation may well be incorrect...
'to' is the link.
Can you help me to learn more?
(Other definitions for forswear that I've seen before include "Denounce" , "Reject or disavow" , "Deny on oath" , "Give up" , "Retract - recant" .)
