Student of French you support on course (5)
I believe the answer is:
tutee
'student' is the definition.
(someone being tutored)
'french you support on course' is the wordplay.
'french you' becomes 'tu' ('you' in French).
'support on course' becomes 'tee' (golf tee on a golf course).
'tu'+'tee'='TUTEE'
'of' is the link.
(Other definitions for tutee that I've seen before include "One learns from a personal teacher" , "Student, pupil" .)
