Slender sounding right to another's property (4)
I believe the answer is:
lien
'right to another's property' is the definition.
I can't judge whether this definition defines the answer.
'slender sounding' is the wordplay.
'slender' becomes 'lean' (similar in meaning).
'sounding' shows a homophone (sound like).
'lean' is a homophone of 'LIEN'.
Can you help me to learn more?
(Other definitions for lien that I've seen before include "Right to another's property, if an obligation is not discharged" , "Legal claim on Nile" , "Security for a debt" , "Right to retain property until a debt is paid" , "Legal right over the Nile" .)
