Small letter possibly read at a meeting (7)
I believe the answer is:
minutes
'at a meeting' is the definition.
I can't tell whether this definition defines the answer.
'small letter possibly' is the wordplay.
'small' becomes 'minute' (similar in meaning).
'letter possibly' becomes 's' (I am not sure about the 'possibly' bit.).
'minute'+'s'='MINUTES'
'read' acts as a link.
Can you help me to learn more?
(Other definitions for minutes that I've seen before include "Record of a meeting" , "Records" , "Recorded notes of a meeting" , "Units of time" , "Record of a meeting's decisions" .)
