Figure, that is, to fade away (3)
I believe the answer is:
die
This could be a double definition.
'figure' is the first definition.
The definition and answer can be both man-made objects as well as being singular nouns.
Perhaps they are linked in a way I don't understand?
'to fade away' is the second definition.
(I've seen this in other clues)
'that is' acts as a link.
Can you help me to learn more?
(Other definitions for die that I've seen before include "Fail" , "Expire" , "Stop functioning" , "Pass from physical life" , "Stamping device" .)
