A little page, fortunate and courageous (6)
I believe the answer is:
plucky
'courageous' is the definition.
(similar in meaning)
'a little page fortunate and' is the wordplay.
'a little' means to remove the last letter (the word is not quite complete).
'page' becomes 'p'.
'fortunate' becomes 'lucky' (similar in meaning).
'and' becomes 'n' (common abbreviation for 'and').
'p'+'lucky'+'n'='pluckyn'
'pluckyn' with its last letter removed is 'PLUCKY'.
(Other definitions for plucky that I've seen before include "Courageous or feisty" , "Showing courage, feisty" , "Brave against odds" , "Determined, courageous" , "Doughty" .)
