Rock outcrop with a British beetle (6)
I believe the answer is:
scarab
'beetle' is the definition.
(scarab is a kind of beetle)
'rock outcrop with a british' is the wordplay.
'rock outcrop with' becomes 'scar' (I can't justify this - if you can you should believe this answer much more).
'british' becomes 'b' (abbreviation e.g. in BBC).
'scar'+'a'+'b'='SCARAB'
Can you help me to learn more?
(Other definitions for scarab that I've seen before include "Sacred beetle of ancient Egypt" , "Large dung beetle" , "Type of beetle" , "divine thing once" , "Beetle revered in ancient Egypt" .)
