The French healer reserving time for teacher (8)
I believe the answer is:
lecturer
'teacher' is the definition.
(I know that lecturer is a type of teacher)
'the french healer reserving time' is the wordplay.
'the french' becomes 'le' ('the' in French).
'healer' becomes 'curer' (someone who heals).
'reserving' means one lot of letters goes inside another (inserted letters get reserved or contained).
'time' becomes 't' (abbreviation).
'curer' placed around 't' is 'cturer'.
'le'+'cturer'='LECTURER'
'for' is the link.
(Other definitions for lecturer that I've seen before include "Speaker" , "University employee" , "Education employee" , "with a penchant for haranguing?" , "Higher-education teacher" .)
