Teacher possibly due to become an actor? (8)
I believe the answer is:
educator
'teacher' is the definition.
(someone who educates)
'possibly due to become an actor?' is the wordplay.
'possibly' is an anagram indicator.
'to become' indicates an anagram.
'due' is an anagram of 'edu'.
'actor' with letters rearranged gives 'cator'.
'edu'+'cator'='EDUCATOR'
(Other definitions for educator that I've seen before include "coach" , "Teacher, lecturer" , "mistress, say" , "Pedagogue, teacher" , "school worker" .)
