Compare almonds around field (5)
I believe the answer is:
realm
'field' is the definition.
(I know that realm is a type of field)
'compare almonds around' is the wordplay.
'around' indicates the answer is hidden within the clue.
'REALM' can be found hidden inside 'compare almonds'.
(Other definitions for realm that I've seen before include "field of study" , "Kingdom, or field of activity" , "Kingdom or sphere" , "region" , "Kingdom; field of interest" .)
