Adventurous recording includes quiet knight returning (12)
I believe the answer is:
enterprising
'adventurous' is the definition.
(I've seen this before)
'recording includes quiet knight returning' is the wordplay.
'recording' becomes 'entering' (enter can mean to enter into a record).
'includes' means one lot of letters goes inside another.
'quiet knight' becomes 'sirp' (I can't justify this - if you can you should give a lot more credence to this answer).
'returning' says the letters should be written in reverse.
'sirp' written backwards gives 'pris'.
'entering' placed around 'pris' is 'ENTERPRISING'.
Can you help me to learn more?
(Other definitions for enterprising that I've seen before include "Showing initiative" , "daring" , "Venturesome" , "Full of initiative" , "Adventurous, resourceful" .)
