Taught wine after time out for revision (7)
I believe the answer is:
tutored
'taught' is the definition.
(tutoring is a kind of teaching)
'wine after time out for revision' is the wordplay.
'wine' becomes 'red' (red is a type of wine).
'after' says to put letters next to each other.
'time' becomes 't' (abbreviation).
'for revision' indicates anagramming the letters (I've seen this in other clues).
'out' is an anagram of 'uto'.
't'+'uto'='tuto'
'red' put after 'tuto' is 'TUTORED'.
(Other definitions for tutored that I've seen before include "Gave private lessons to" , "Instructed" , "Privately taught" , "Was coach" , "Disciplined" .)
