Charge for delivering pages to be edited (7)
I believe the answer is:
postage
'charge for' is the definition.
The definition and answer can be both related to communication as well as being singular nouns.
Maybe you can see a link between them that I don't see?
'pages to be edited' is the wordplay.
'be edited' indicates anagramming the letters.
'pages'+'to'='pagesto'
'pagesto' with letters rearranged gives 'POSTAGE'.
'delivering' is the link.
Can you help me to learn more?
(Other definitions for postage that I've seen before include "Cost to send a mail item" , "It could be first-class" , "Amount paid to mail" , "Money charged for delivery" , "Cost of corresponding" .)
