Where one shifts stuff from the estate? (3,4,4)
I believe the answer is:
car boot sale
'where one shifts stuff' is the definition.
I know nothing about this answer so I can't tell whether it can be defined by this definition.
'from the estate?' is the wordplay.
I cannot really see how this works, but
'from' could be 'o' (I've seen this in other clues) and 'o' is found in the answer.
'the' could be 't' (the is pronounced as a 't' sound in some dialects) and 't' is located in the answer.
'estate?' could be 'car' (estate is a type of car) and 'car' is located in the answer.
This explanation may well be incorrect...
Can you help me to learn more?
(Other definitions for car boot sale that I've seen before include "field event?" , "Vending of second-hand goods from private vehicles" , "Event involving trade conducted from the back of one's vehicle" , "Where unwanted possessions may be disposed of" , "Second hand market" .)
