Associate bishop in viral image with rook (6)
I believe the answer is:
member
'associate' is the definition.
(member is a kind of associate)
'bishop in viral image with rook' is the wordplay.
'bishop' becomes 'b' (abbreviation used in chess).
'in' means one lot of letters goes inside another.
'viral image' becomes 'meme' (I am not sure about this - if you are sure you should believe this answer much more).
'with' means one lot of letters go next to another.
'rook' becomes 'r' (abbreviation in chess).
'b' placed into 'meme' is 'membe'.
'membe'+'r'='MEMBER'
Can you help me to learn more?
(Other definitions for member that I've seen before include "Part of body or club associate" , "Limb, MP" , "One belongs to a group" , "Limb - element - one in society" , "Part of body or one of a group" .)
