Can see improvement at meeting (6)
I believe the answer is:
seance
'meeting' is the definition.
(I know that seance is a type of meeting)
'can see improvement' is the wordplay.
'can see' can be anagrammed to 'SEANCE'.
However, I'm unsure how this is indicated.
'at' is the link.
Can you help me to learn more?
(Other definitions for seance that I've seen before include "Spirit-raising" , "Spiritualist meeting, all hold hands" , "Sitting, session" , "spiritual guidance" , "Meeting held by a medium" .)
