Profile of both sides fall from grace (4)
I believe the answer is:
face
'grace' is the definition.
The answer and definition can be both human attributes as well as being singular nouns.
Perhaps you can see an association between them that I can't see?
'profile of both sides fall' is the wordplay.
'profile of' becomes 'fa' (I can't explain this - if you can you should give a lot more credence to this answer).
'both sides' means to remove the middle letters (I've seen 'both sides of' mean this (only the letters on the sides remain)).
'fall' becomes 'come' (synonyms).
'come' with its middle removed is 'ce'.
'fa'+'ce'='FACE'
'from' acts as a link.
Can you help me to learn more?
(Other definitions for face that I've seen before include "set of features" , "Cope with" , "TV show" , "well-known person" , "'Cheeks, mouth, eyes etc (4)'" .)
