Prudence West is taking Benedictine (6)
I believe the answer is:
wisdom
'prudence' is the definition.
(I've seen this before)
'west is taking benedictine' is the wordplay.
'west' becomes 'W' (abbreviation).
'taking benedictine' becomes 'dom' (I can't justify this - if you can you should believe this answer much more).
'w'+'is'+'dom'='WISDOM'
Can you help me to learn more?
(Other definitions for wisdom that I've seen before include "Put forward (an idea)" , "Erudition" , "Learning, knowledge" , "Combination of experience, knowledge and good judgement" , "Common sense" .)
