Nothing recalled about English legal right (4)
I believe the answer is:
lien
'legal right' is the definition.
(I've seen this before)
'nothing recalled about english' is the wordplay.
'nothing' becomes 'nil' ('nil' can be a synonym of 'nothing'**).
'recalled' is a reversal indicator.
'about' is an insertion indicator.
'english' becomes 'e' (abbreviation).
'nil' reversed gives 'lin'.
'lin' placed around 'e' is 'LIEN'.
(Other definitions for lien that I've seen before include "Right to keep property" , "Legal claim on the property of another" , "Right to retain property until a debt is paid" , "The right to take property if an obligation is not met" , "Legal right over the Nile" .)
