Sausage in crate (6)
I believe the answer is:
banger
This could be a double definition.
'sausage' is the first definition.
(banger is a kind of sausage)
'crate' is the second definition.
The answer and definition can be both man-made objects as well as being singular nouns.
Maybe there's an association between them I don't understand?
'in' is the link.
Can you help me to learn more?
(Other definitions for banger that I've seen before include "Clapped-out car" , "Noisy old car or slang sausage" , "Explosive" , "Slangily, a noisy old car or a sausage" , "Meaty" .)
