Pages man at rest? That is wrong (8)
I believe the answer is:
chapters
'pages' is the definition.
The answer and definition can be both related to communication as well as being plural nouns.
Maybe you can see an association between them that I can't see?
'man at rest? that is wrong' is the wordplay.
'man' becomes 'chap' (I've seen this in other clues).
'at' means one lot of letters go next to another.
'that is wrong' is an anagram indicator.
'rest' anagrammed gives 'ters'.
'chap'+'ters'='CHAPTERS'
Can you help me to learn more?
(Other definitions for chapters that I've seen before include "Divisions of written work" , "Numbered sections of a book" , "Divisions of a book" , "Local branches of fraternity or association" , "Episodes" .)
