They make a quiet approach, putting a point to lecturers (8)
I believe the answer is:
stalkers
'lecturers' is the definition.
The answer and definition can be both people as well as being plural nouns.
Maybe there's an association between them I don't understand?
I cannot understand how the rest of the clue works.
Can you help me to learn more?
(Other definitions for stalkers that I've seen before include "They follow people with sinister intent" , "They track animals - or follow people" , "People who pursue others stealthily, as some men do women" , "They stealthily follow people or animals" .)
