Lecture from judge creating dread (6)

I believe the answer is:

jawing

'lecture' is the definition.
(to jaw is to talk at length)

'judge creating dread' is the wordplay.
'judge' becomes 'j'.
'creating dread' becomes 'awing'.
'j'+'awing'='JAWING'

'from' acts as a link.

(Other definitions for jawing that I've seen before include "Win Jag (anag)" , "Gossip" .)

I've seen this clue in The Guardian.
