Express disapproval about one item that's charged in lessons (7)
I believe the answer is:
tuition
'lessons' is the definition.
(I've seen this before)
'express disapproval about one item that's charged' is the wordplay.
'express disapproval about' becomes 'tu' (I can't justify this - if you can you should believe this answer much more).
'one item' becomes 'it' (I've seen this in other clues).
'that's charged' becomes 'ion' (I've seen this in other clues).
'tu'+'it'+'ion'='TUITION'
'in' acts as a link.
Can you help me to learn more?
(Other definitions for tuition that I've seen before include "practice" , "Personal coaching" , "Training" , "Schooling" , "Teaching, instruction" .)
