Oversupply from the East (4)
I believe the answer is:
sate
'oversupply' is the definition.
Although both the answer and definition are verbs in their base form, I don't understand how one could define the other.
'the east' is the wordplay.
'east' anagrams to 'SATE'.
Though, I'm not sure how this is indicated.
'from' is the link.
Can you help me to learn more?
(Other definitions for sate that I've seen before include "Satisfy - surfeit" , "Satisfy to the full" , "Stuff with teas" , "spicy meat" , "Overfill, gratify" .)
