Brave little Penny - and fortunate, too (6)
I believe the answer is:
plucky
'brave little' is the definition.
'plucky' can be an answer for 'brave' (I've seen this before). I am not certain of the 'little' bit.
'penny and fortunate too' is the wordplay.
I cannot quite see how this works, but
'penny' could be 'p' (short for pence) and 'p' is located in the answer.
'fortunate' could be 'lucky' (similar in meaning) and 'lucky' is located in the answer.
No letters remain.
This explanation may well be incorrect...
Can you help me to learn more?
(Other definitions for plucky that I've seen before include "Game" , "Brave, showing courage" , "Valorous" , "Showing courage, feisty" , "Brave against odds" .)
