Stick firm to this place (6)
I believe the answer is:
cohere
'stick' is the definition.
('cohere' can be a synonym of 'stick')
'firm to this place' is the wordplay.
'firm' becomes 'co' (a firm is a company).
'to this place' becomes 'here' ('here' can be a synonym of 'to this place'**).
'co'+'here'='COHERE'
(Other definitions for cohere that I've seen before include "Hold firmly together" , "Cling" , "Form a whole" , "Fuse together" , "Stick or hold together and resist separation" .)
