Figure no longer living in the past, note (7)
I believe the answer is:
decagon
'figure' is the definition.
(type of geometrical figure)
'no longer living in the past note' is the wordplay.
'no longer living' becomes 'dec' (abbreviation for deceased).
'in the past' becomes 'ago' (synonyms).
'note' becomes 'n' (abbreviation).
'dec'+'ago'+'n'='DECAGON'
(Other definitions for decagon that I've seen before include "Ten-sided plane figure" , "10-sided figure" , "Figure with 10 sides" , "Go, dance on geometric figure with ten sides" , "Plane shape" .)
