See fit to follow (7)
I believe the answer is:
conform
'follow' is the definition.
(thesaurus)
'see fit' is the wordplay.
I cannot really understand how this works, but
'see' could be 'c' (the word for the letter, according to Chambers) and 'c' is present in the answer.
'fit' could be 'onform' (I've seen this before) and 'onform' is found within the answer.
No letters remain.
This explanation may well be incorrect...
'to' is the link.
Can you help me to learn more?
(Other definitions for conform that I've seen before include "Comply with accepted rules" , "Toe the line" , "become fitter?" , "Follow the crowd" , "Adapt" .)
