Determination to tackle puzzle again (7)
I believe the answer is:
resolve
'determination' is the definition.
(I've seen this before)
'tackle puzzle again' is the wordplay.
I cannot quite understand how this works, but
'again' could be 're' (prefix meaning 'again') and 're' is found in the answer.
The remaining letters 'solve' is a valid word which might be clued in a way I don't understand.
This explanation may well be incorrect...
'to' is the link.
Can you help me to learn more?
(Other definitions for resolve that I've seen before include "find an answer" , "Be determined" , "work out" , "Settle (a matter)" , "Determine with conviction" .)
