Richard's bluff? (5)
I believe the answer is:
cliff
This clue could be a double definition.
'richard's' is the first definition.
Both the answer and definition are singular nouns.
Perhaps there's an association between them I don't understand?
'bluff?' is the second definition.
(bluff can mean a cliff)
Can you help me to learn more?
(Other definitions for cliff that I've seen before include "A steep rock-face on coast" , "High, steep rock face" , "-- Richard, singer" , "stony face?" , "Precipice" .)
