The Sage of Concord (7)
I believe the answer is:
emerson
'the sage of concord' is the definition.
(I've seen this in another clue)
This is the entire clue.
(Other definitions for emerson that I've seen before include "Individualist" , "American author, 1803-82" , "American poet and philosopher, d. 1882" , "--, Lake and Palmer, rock group" , "Ralph Waldo . . ., 19th century American philosopher and poet" .)
