Lecturer whipped cheat with little hesitation (7)
I believe the answer is:
teacher
'lecturer' is the definition.
(I've seen this before)
'whipped cheat with little hesitation' is the wordplay.
'whipped' indicates anagramming the letters.
'with' is a charade indicator (letters next to each other).
'little hesitation' becomes 'er'.
'cheat' anagrammed gives 'teach'.
'teach'+'er'='TEACHER'
(Other definitions for teacher that I've seen before include "The trainer" , "CARRY ON FILM" , "Cheater (anag.)" , "Tutor" , "Guide" .)
