Comedian displaying French shrewdness? (6,6)
'comedian' is the definition.
Both the definition and answer are singular nouns.
Perhaps there's a link between them I don't understand?
'french shrewdness?' is the wordplay.
'french' becomes 'norman' (Normandy is a part of France).
'shrewdness?' becomes 'wisdom' (I can't justify this - if you can you should give a lot more credence to this answer).
'displaying' is the link.
Can you help me to learn more?
(Other definitions for norman wisdom that I've seen before include "English comic actor, famed for hapless on-screen roles, d. 2010", "Pearls from Rouen, maybe", "funny little bloke in a flat cap", "old actor", "British comedian, once a cult figure in Albania, d. 2010".)
