Container of pecan nuts (3)
I believe the answer is:
can
'container' is the definition.
(can is a kind of container)
'of pecan nuts' is the wordplay.
'of' indicates the answer is hidden within the clue.
'CAN' is hidden within 'pecan nuts'.
(Other definitions for can that I've seen before include "May" , "Preserve fruit" , "let go in the US" , "depth charge" , "prison" .)
