Agreed apparently to make amends (5)
I believe the answer is:
atone
'make amends' is the definition.
(to atone is to make amends for a wrong deed)
'agreed apparently to' is the wordplay.
I cannot really understand how this works, but
'to' is within the answer.
The remaining letters 'ane' is a valid word which might be clued in a way I don't understand.
This explanation may well be incorrect...
Can you help me to learn more?
(Other definitions for atone that I've seen before include "Adopt a cause" , "Make good" , "Make up for wrong done" , "Make amends (for something)" , "Recompense" .)
