Instructor having drink with pop star (7)
I believe the answer is:
teacher
'instructor' is the definition.
(I know that instructor can be written as teacher)
'drink with pop star' is the wordplay.
'drink' becomes 'tea' (tea is a drink).
'with' is a charade indicator (letters next to each other).
'pop star' becomes 'cher' (I have seen 'Moonstruck star' mean 'cher' so perhaps 'star' could also mean 'cher'. I am not sure about the 'pop' bit.).
'tea'+'cher'='TEACHER'
'having' acts as a link.
Can you help me to learn more?
(Other definitions for teacher that I've seen before include "one of the staff" , "Master" , "The race (anag.)" , "Tutor" , "CARRY ON FILM" .)
