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' means one lot of letters goes inside another.
'flipping' says the letters should be written in reverse.
'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" .)
