Teacher to express displeasure with men (5)
I believe the answer is:
tutor
'teacher' is the definition.
(tutor is a kind of teacher)
'express displeasure with men' is the wordplay.
'express displeasure' becomes 'tut' (**).
'with' says to put letters next to each other.
'men' becomes 'or' (I've seen this in other clues).
'tut'+'or'='TUTOR'
'to' acts as a link.
(Other definitions for tutor that I've seen before include "Personal coach" , "Teach" , "School" , "trainer" , "Private instructor" .)
