Crossword Genius

In talk, entice to accept shocking treatment (7)

Ross

I believe the answer is:

lecture

'in talk' is the definition.
'lecture' can be an answer for 'talk' (synonyms). I am unsure of the 'in' bit.

'entice to accept shocking treatment' is the wordplay.
'entice' becomes 'lure' (synonyms).
'to accept' is an insertion indicator.
'shocking treatment' becomes 'ect' (electro-convulsive therapy).
'lure' enclosing 'ect' is 'LECTURE'.

(Other definitions for lecture that I've seen before include "University talk" , "Sermon" , "Class at university" , "Formal talk on a subject" , "Instructional talk" .)

I've seen this clue in The Guardian.
