Female accepts writing on the wall in later years (6)
I believe the answer is:
dotage
'later years' is the definition.
'female accepts writing on the wall' is the wordplay.
'female' becomes 'doe' (I've seen this before).
'accepts' indicates putting letters inside.
'writing on the wall' becomes 'tag' (graffiti).
'doe' going around 'tag' is 'DOTAGE'.
'in' is the link.
(Other definitions for dotage that I've seen before include "Feeble-minded period late in life" , "Mental infirmity in old age" , "Feeble later life" , "Foolish later life" , "Old and weak time of life" .)
