A lot of stuff, I sense, can be sticky (9)
I believe the answer is:
glutinous
'be sticky' is the definition.
('glutinous' can be a synonym of 'sticky')
'a lot of stuff i sense' is the wordplay.
'a lot of stuff' becomes 'glut'.
'sense' becomes 'nous' (nous is a kind of sense).
'glut'+'i'+'nous'='GLUTINOUS'
'can' acts as a link.
(Other definitions for glutinous that I've seen before include "not easy to shake off?" , "Sticky" .)
