Glut of butter in the southeast? (5)
I believe the answer is:
spate
'glut' is the definition.
Although both the answer and definition are singular nouns, I cannot see how one could define the other.
'butter in the southeast?' is the wordplay.
'butter' becomes 'pat' (a pat can mean a lump of butter).
'in the' means one lot of letters goes inside another.
'southeast?' becomes 'SE' ('SE' can be a synonym of 'southeast').
'pat' placed within 'se' is 'SPATE'.
'of' is the link.
Can you help me to learn more?
(Other definitions for spate that I've seen before include "rash" , "Fast outpouring" , "A sudden flood or rush" , "Suddenly got a lot" , "Rush, flood (of river)" .)
