Centre; courage (5)
I believe the answer is:
heart
This clue is a double definition.
'centre' is the first definition.
(I know that centre can be written as heart)
'courage' is the second definition.
(I know that heart is a type of courage)
(Other definitions for heart that I've seen before include "See 22" , "Pumping organ" , "Cardiac organ" , "Core, courage" , "Body organ" .)
