Time for a drink (3)
I believe the answer is:
tea
'a drink?' is the definition.
(tea is a drink)
'time for' is the wordplay.
'time' becomes 't' (abbreviation).
'for' becomes 'ea' (I can't justify this - if you can you should give a lot more credence to this answer).
't'+'ea'='TEA'
Can you help me to learn more?
(Other definitions for tea that I've seen before include "Refresher course" , "- - for Two (song)" , "and 18 Across: Utensils for afternoon meal" , "US party" , "For Japanese ceremony" .)
