Agreed to gorge, maybe, after getting round brief food shortage (2,1,4)
I believe the answer is:
of a mind
'agreed' is the definition.
(I've seen this before)
'gorge maybe after getting round brief food shortage' is the wordplay.
'gorge maybe' becomes 'd' (I can't justify this - if you can you should give a lot more credence to this answer).
'after' says to put letters next to each other.
'getting round' becomes 'o' (I've seen this in other clues).
'brief' means to remove the last letter.
'food shortage' becomes 'famine' (I've seen this before).
'famine' with its final letter removed is 'famin'.
'o'+'famin'='ofamin'
'd' after 'ofamin' is 'OF A MIND'.
'to' is the link.
(Other definitions for of a mind that I've seen before include "Agreed" , "In accord" .)
