Is there an intended audience for a book, or intended readers? I want to say the targeted sphere of people that would buy and read the book. I mean, for whom the book was written. How do you say it better? To my ear for some reason audience sounds better
You can refer to the “intended readers“ as target readership or audience.”
a target audience is the intended audience or readership of a publication, advertisement, or other message catered specifically to said the intended audience.
