Prince needing good fortune and courage (5)
I believe the answer is:
pluck
'courage' is the definition.
(I've seen this before)
'prince needing good fortune' is the wordplay.
'prince' becomes 'p'.
'needing' means one lot of letters go next to another.
'good fortune' becomes 'luck' (I've seen this before).
'p'+'luck'='PLUCK'
'and' acts as a link.
(Other definitions for pluck that I've seen before include "Gather" , "Courage - play a harp" , "Courage - defeather" , "Determined courage" , "extract" .)
