Lecture embraced by educator, a test (5)
I believe the answer is:
orate
'lecture' is the definition.
(I've seen this before)
'embraced by educator a test' is the wordplay.
'embraced by' says the answer is hidden in the clue (surrounding letters embrace the answer).
'ORATE' is hidden within 'educator a test'.
(Other definitions for orate that I've seen before include "Give a formal address" , "Speak like Cicero?" , "Speechify" , "Declaim or rant" , "Speak formally" .)
