Large containers of nuts (4)
I believe the answer is:
tuns
'large containers' is the definition.
'tuns' can be an answer for 'containers' (tun is a kind of container). I'm not certain of the 'large' bit.
'of nuts' is the wordplay.
'of' indicates anagramming the letters (the answer comes from or 'of' the letters).
'nuts' anagrammed gives 'TUNS'.
Can you help me to learn more?
(Other definitions for tuns that I've seen before include "Containers" , "Large casks" , "barrels" .)
