Speak in terror at educational (5)
I believe the answer is:
orate
'speak' is the definition.
(orating is a kind of speaking)
'in terror at educational' is the wordplay.
'in' says the answer is hidden in the clue.
'ORATE' is hidden in the letters of 'terror at educational'.
(Other definitions for orate that I've seen before include "Spout" , "Speaker may" , "Make a flowery speech" , "Make a formal address" , "Make a formal speech" .)
