Large containers of nuts (4)
I believe the answer is:
tuns
This could be a double definition.
'large containers' is the first definition.
'tuns' can be an answer for 'containers' (tun is a kind of container). I am not sure about the 'large' bit.
'nuts' is the second definition.
The answer and definition can be both man-made objects as well as being plural nouns.
Maybe there's an association between them I don't understand?
'of' acts as a link.
Can you help me to learn more?
(Other definitions for tuns that I've seen before include "Containers" , "Large casks" , "barrels" .)
