Grifter's confession diplayed on computer (4)
I believe the answer is:
icon
'computer' is the definition.
The answer and definition can be both man-made objects as well as being singular nouns.
Maybe you can see a link between them that I don't see?
'grifter's confession diplayed on' is the wordplay.
I cannot really see how this works, but
'on' is found in the answer.
This explanation may well be incorrect...
Can you help me to learn more?
(Other definitions for icon that I've seen before include "found on computer screen" , "Image of a religious figure" , "Devotional image (C, not K)" , "Holy image or symbol on computer screen" , "representing a saint?" .)
