School backed legal action — there's usually money in it (8)
I believe the answer is:
notecase
'usually money in it' is the definition.
I can't tell whether this definition defines the answer.
'school backed legal action' is the wordplay.
'school' becomes 'eton' (famous UK public school).
'backed' says the letters should be written backwards.
'legal action' becomes 'case' ('case' can be a synonym of 'legal action').
'eton' reversed gives 'note'.
'note'+'case'='NOTECASE'
'there's' is the link.
Can you help me to learn more?
(Other definitions for notecase that I've seen before include "Wallet for paper money" , "carrier of cash" , "Wallet for folding money" , "Container for paper money" , "used to carry money" .)
