Stick of jade uncovered in this place (6)
I believe the answer is:
adhere
'stick' is the definition.
(to adhere to something is to stick to it)
'jade uncovered in this place' is the wordplay.
'uncovered' says to take the centre.
'in this place' becomes 'here' (synonyms).
The middle of 'jade' is 'ad'.
'ad'+'here'='ADHERE'
'of' is the link.
(Other definitions for adhere that I've seen before include "paste" , "Cling, attach" , "Stick to or continue faithful" , "Stick to - cement" , "Stick L" .)
