Abraham's nephew up for auction? (3)
I believe the answer is:
lot
'abraham's nephew' is the definition.
(I've seen this before)
'up for auction?' is the wordplay.
'up' says the letters should be written in reverse (in down clue: letters go upwards).
'for' becomes 'to' (eg both can mean 'in the opinion of').
'auction?' becomes 'l' (I can't justify this - if you can you should give a lot more credence to this answer).
'to'+'l'='tol'
'tol' backwards is 'LOT'.
Can you help me to learn more?
(Other definitions for lot that I've seen before include "Kismet" , "Destiny - auction item(s)" , "Share - tons" , "Large amount; Abraham's nephew" , "Destiny; auction item" .)
