Look after article in flipping memory (6)
I believe the answer is:
mother
'look after' is the definition.
(thesaurus)
'article in flipping memory' is the wordplay.
'article' becomes 'the' (the definite article in English).
'in' is an insertion indicator.
'flipping' says the letters should be written backwards.
'memory' becomes 'ROM' (Read-Only Memory on a computer).
'rom' in reverse letter order is 'mor'.
'the' put within 'mor' is 'MOTHER'.
(Other definitions for mother that I've seen before include "She gives birth" , "- - 7 across, pantomime" , "Nature so-called" , "Parent to her Tom, oddly" , "She gave birth to her Tom" .)
