Missing or sold at auction? (4)
I believe the answer is:
gone
'missing' is the definition.
(synonyms)
'sold at auction?' is the wordplay.
I cannot really see how this works, but
'at' could be 'on' (location) and 'on' is found within the answer.
The remaining letters 'ge' is a valid word which might be clued in a way I don't see.
This explanation may well be incorrect...
'or' acts as a link.
Can you help me to learn more?
(Other definitions for gone that I've seen before include "Departed, left" , "No longer present" , "Departed, disappeared" , "Departed; used up" , "Departed or dead" .)
