Poignant, timeless article describing female relative (8)
I believe the answer is:
haunting
'poignant' is the definition.
(I've seen this before)
'timeless article describing female relative' is the wordplay.
'timeless article' becomes 'hing' (I am not sure about this - if you are sure you should believe this answer much more).
'describing' is an insertion indicator (describe can mean to form the outline of).
'female relative' becomes 'aunt' (I've seen this before).
'hing' placed around 'aunt' is 'HAUNTING'.
Can you help me to learn more?
(Other definitions for haunting that I've seen before include "A show of spirit" , "difficult to forget" , "Poignant, evocative" , "Frequenting a place, as a ghost might" , "Visiting as a ghost" .)
