Collected points at appointment (6)
I believe the answer is:
sedate
'collected' is the definition.
(I've seen this before)
'points at appointment' is the wordplay.
'points' becomes 'se'.
'at' says to put letters next to each other.
'appointment' becomes 'date' (synonyms).
'se'+'date'='SEDATE'
(Other definitions for sedate that I've seen before include "Calm and demure" , "Prim and proper" , "Calm, unhurried" , "Quiet and dignified" , "Decorous" .)
