Be determined to do the puzzle again? (7)
I believe the answer is:
resolve
'be determined' is the definition.
(I've seen this before)
'do the puzzle again?' is the wordplay.
I cannot really see how this works, but
'again?' could be 're' (prefix meaning 'again') and 're' is located in the answer.
The remaining letters 'solve' is a valid word which might be clued in a way I don't see.
This may be the basis of the clue (or it may be nonsense).
'to' acts as a link.
Can you help me to learn more?
(Other definitions for resolve that I've seen before include "Find the solution (to)" , "Settle (a dispute)" , "bottle" , "Willpower" , "Settle, conclude" .)
