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' means to look at the middle letters.
'in this place' becomes 'here' (synonyms).
The central letters of 'jade' are '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" .)
