Recaps plot about form of delivery (6,4)
I believe the answer is:
parcel post
'form of delivery' is the definition.
The definition and answer can be both related to communication as well as being singular nouns.
Maybe there's an association between them I don't understand?
'recaps plot about' is the wordplay.
'about' is an anagram indicator.
'recaps'+'plot'='recapsplot'
'recapsplot' is an anagram of 'PARCEL POST'.
Can you help me to learn more?
(Other definitions for parcel post that I've seen before include "How something's sent" , "Means of sending packages" , "Mail service" .)
