Carrier of half a bushel (3)
I believe the answer is:
bus
'carrier' is the definition.
The definition and answer can be both man-made objects as well as being singular nouns.
Perhaps you can see an association between them that I don't see?
'half a bushel' is the wordplay.
'half a' means to take half the letters.
'bushel' halved is 'BUS'.
'of' acts as a link.
Can you help me to learn more?
(Other definitions for bus that I've seen before include "People carrier" , "Use transport" , "Coach" , "Large passenger vehicle - small business!" , "Public transport vehicle" .)
