Supply making expert sense (9)
I believe the answer is:
provision
'supply' is the definition.
(synonyms)
'expert sense' is the wordplay.
'expert' becomes 'pro' (short for professional).
'sense' becomes 'vision' (vision is a kind of sense).
'pro'+'vision'='PROVISION'
'making' acts as a link.
(Other definitions for provision that I've seen before include "facilities" , "Supply; condition" , "prior measures made" , "Something supplied" , "Keep supplied" .)
