Flog students, following directions (4)
I believe the answer is:
sell
'flog' is the definition.
(I know that flog can be written as sell)
'students following directions' is the wordplay.
'students' becomes 'LL' (an abbreviation for learner driver written twice).
'following' says to put letters next to each other.
'directions' becomes 'se' (I've seen this in other clues).
'll' after 'se' is 'SELL'.
(Other definitions for sell that I've seen before include "Vend, auction off" , "Exchange goods etc. for money" , "Peddle" , "Flog" , "Dispose of for money" .)
