Tea's brewed for tucker (4)
I believe the answer is:
eats
'tucker' is the definition.
Although both the answer and definition are singular nouns, I don't see how one could define the other.
'tea's brewed' is the wordplay.
'brewed' indicates an anagram.
'teas' with letters rearranged gives 'EATS'.
'for' is the link.
Can you help me to learn more?
(Other definitions for eats that I've seen before include "fare" , "Chews" , "Takes food" , "Sate (anag.)" , "Provisions" .)
