Ignore info returned by the French court (7)
I believe the answer is:
neglect
'ignore' is the definition.
(I know that ignore can be written as neglect)
'info returned by the french court' is the wordplay.
'info' becomes 'gen' (informal term for information).
'returned' shows that the letters should be reversed in order.
'by' is a charade indicator (letters next to each other).
'the french' becomes 'le' ('the' in French).
'court' becomes 'ct' (abbreviation used in road names).
'gen' reversed gives 'neg'.
'neg'+'le'+'ct'='NEGLECT'
(Other definitions for neglect that I've seen before include "slight" , "Heedlessness" , "Fail to take proper care of, be derelict" , "Lack of proper care" , "Omit by carelessness" .)
