Time to eat? (3)
'time' is the definition.
Although both the answer and definition are singular nouns, I cannot see how one could define the other.
'eat?' is the wordplay.
'eat' anagrams to 'TEA'.
Though, I'm unsure how this is indicated.
'to' is the link.
Can you help me to learn more?
(Other definitions for tea that I've seen before include "The cup that cheers but not inebriates" , "Evening meal - eat up" , "US party" , "A light meal - eat up" , "Common drink" .)
