Teacher after wine and ginger (7)
I believe the answer is:
redhead
'ginger' is the definition.
(both can mean someone with red hair)
'teacher after wine' is the wordplay.
'teacher' becomes 'head'.
'after' means one lot of letters go next to another.
'wine' becomes 'red' (red is a type of wine).
'head' put after 'red' is 'REDHEAD'.
'and' acts as a link.
(Other definitions for redhead that I've seen before include "Person with distinctive coloured hair" , "One with auburn hair" , "One with distinctive hair" , "member of ginger group?" , "Ginger-haired person" .)
