Teaching you French, I get into trouble (7)
I believe the answer is:
tuition
'teaching' is the definition.
(tuition is a kind of teaching)
'you french i get into trouble' is the wordplay.
'you french' becomes 'tu' (I've seen this in other clues).
'get' says to put letters next to each other.
'trouble' indicates anagramming the letters.
'into' anagrammed gives 'tion'.
'tu'+'i'+'tion'='TUITION'
(Other definitions for tuition that I've seen before include "Teaching, instruction" , "Teaching, often one-to-one" , "Lessons" , "(Individual) instruction" , "Schooling" .)
