Stick notice at this point (6)
I believe the answer is:
adhere
'stick' is the definition.
('adhere' can be a synonym of 'stick')
'notice at this point' is the wordplay.
'notice' becomes 'ad'.
'at this point' becomes 'here' (I've seen this before).
'ad'+'here'='ADHERE'
(Other definitions for adhere that I've seen before include "Hold fast, stand by" , "Stick - join" , "Keep" , "Stick L" , "Stick to, remain loyal" .)
