Can see improvement in 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' anagrams to 'SEANCE'.
But, I am not sure how this is indicated.
'in' is the link.
Can you help me to learn more?
(Other definitions for seance that I've seen before include "Spiritualist session with medium in charge" , "Session of spritualists" , "spiritual guidance" , "Psychic gathering" , "Spirit meeting" .)
