Drive little devil to the school finally (5)
I believe the answer is:
impel
'drive' is the definition.
(thesaurus)
'little devil to the school finally' is the wordplay.
'little devil' becomes 'imp' (I've seen this before).
'finally' indicates one should take the final letters.
The last letters of 'the school' are 'el'.
'imp'+'el'='IMPEL'
(Other definitions for impel that I've seen before include "Urge forward - push" , "Motivate" , "Hold together" , "Goad" , "Urge or propel" .)
