Chatter with teacher before start of tutorial (6)
I believe the answer is:
rabbit
'chatter' is the definition.
(I've seen this before)
'teacher before start of tutorial' is the wordplay.
'teacher' becomes 'rabbi' (I've seen this before).
'before' says to put letters next to each other.
'start of' says to take the initial letters.
The first letter of 'tutorial' is 't'.
'rabbi'+'t'='RABBIT'
'with' acts as a link.
(Other definitions for rabbit that I've seen before include "Chatter; poor games-player" , "Chatter; mammal" , "Inferior sportsman" , "bun?" , "Burrowing animal or rotten tennis player" .)
