IPA: //nɒnˈvjuːər//
KK: /nɑnˈvjʊər/
A person who does not watch something, especially television or a specific program.
As a nonviewer of the show, I had no idea what everyone was talking about.
Nonviewer → It is formed from "non-" (meaning not) and "viewer" (from Old French *veoir*, meaning to see). The word "nonviewer" refers to someone who does not see or watch something.
Think of 'not' ('non-') and 'seeing' ('viewer') to remember that a nonviewer is someone who does not watch or see.
