Confused Piers heard subscribers (10)
I believe the answer is:
readership
'confused piers heard subscribers' is the definition.
I can't judge whether this definition defines the answer.
'confused piers heard' is the wordplay.
'confused' indicates anagramming the letters.
'piers'+'heard'='piersheard'
'piersheard' with letters rearranged gives 'READERSHIP'.
Can you help me to learn more?
(Other definitions for readership that I've seen before include "university post" , "academic position" , "People perusing paper" , "a position at university -" , "Maybe all those enjoying Plath" .)
