Detailed section in record of meeting (7)
I believe the answer is:
minutes
This clue could be a double definition.
'detailed section' is the first definition.
The answer and definition can be both related to communication as well as being singular nouns.
Perhaps there's a link between them I don't understand?
'record of meeting' is the second definition.
(I've seen this before)
'in' acts as a link.
Can you help me to learn more?
(Other definitions for minutes that I've seen before include "summary" , "Record of a meeting" , "Record of a meeting's decisions" , "Units of time" , "Recorded notes of a meeting" .)
