Cruelly rag one born under the Ram sign from land property (8)
I believe the answer is:
agrarian
'land property' is the definition.
Both the answer and definition are adjectives. Maybe you can see a link between them that I don't see?
'cruelly rag one born under the ram sign' is the wordplay.
'cruelly' indicates an anagram (I've seen this in other clues).
'one born' becomes 'n'.
'under' means one lot of letters go next to another.
'the ram sign' becomes 'aria' (I can't justify this - if you can you should give a lot more credence to this answer).
'rag' is an anagram of 'agr'.
'n' put after 'aria' is 'arian'.
'agr'+'arian'='AGRARIAN'
'from' acts as a link.
Can you help me to learn more?
(Other definitions for agrarian that I've seen before include "Relating to the cultivation of land" , "kind of revolution" , "Land reformer" , "Concerned with land management" , "in the country" .)
