Stick notes to this place (6)
I believe the answer is:
Here is my best explanation:
'stick' is the definition.
('adhere' can be a synonym of 'stick')
'notes to this place' is the subsidiary indication.
'notes' becomes 'ad'.
'to this place' becomes 'here' (I've seen this in other clues).
(Other definitions for adhere that I've seen before include "Remain faithful", "Stick - join", "Bond", "Stick to as by suction", "Stick to - cement", "Stick to or remain faithful", "Stick firmly", "Stick L", "secure" and "Stick or cleave to".)
