Finds out that money constitutes a snare (6)
I believe the answer is:
learns
'finds out that' is the definition.
'learns' can be an answer for 'finds out' (I've seen this before). I'm not certain of the remainder of the definition.
'money constitutes a snare' is the wordplay.
'money' becomes 'l' (L can mean 'pounds').
'constitutes a snare' becomes 'earns' (I can't explain this - if you can you should believe this answer much more).
'l'+'earns'='LEARNS'
Can you help me to learn more?
(Other definitions for learns that I've seen before include "Finds out" , "Teaches non-standard" , "Gains understanding from study or experience" , "Gains knowledge or skill" , "Gains knowledge or skills" .)
