Lesson of love in practice following you French (8)
I believe the answer is:
tutorial
'lesson' is the definition.
(I've seen this before)
'love in practice following you french' is the wordplay.
'love' becomes 'o' (In tennis, 'love' means 'zero').
'in' indicates putting letters inside.
'practice' becomes 'trial'.
'following' means one lot of letters go next to another.
'you french' becomes 'tu' (I've seen this in other clues).
'o' put within 'trial' is 'torial'.
'torial' after 'tu' is 'TUTORIAL'.
'of' acts as a link.
(Other definitions for tutorial that I've seen before include "University lesson" , "Session of intensive teaching to an individual or small group" , "Seminar" , "A period of individual tuition" , "Personal teaching session" .)
