Gullible person gets some coffee (3)
I believe the answer is:
mug
This might be a double definition.
'gullible person' is the first definition.
(mug can mean a gullible or foolish person)
'some coffee' is the second definition.
Although both the answer and definition are singular nouns, I cannot see how they can define each other.
'gets' is the link.
Can you help me to learn more?
(Other definitions for mug that I've seen before include "Face; cup; rob" , "Drinking vessel; rob" , "Vessel for a bit of a fool" , "Fool - face - vessel" , "concentrate on studying" .)
