KK: /ˈnjuːzwɜːrðɪnəs/
The quality or importance of a story or event that makes it suitable to be reported in the news.
The newsworthiness of the event attracted many journalists.
Newsworthiness → It is formed from "news" (from Old English *news*, meaning new things or information) and "-worthiness" (from Old English *wyrðe*, meaning worthy or deserving). The word "newsworthiness" refers to the quality of being worthy of being reported as news.
Think of 'new things' ('news') that are 'worthy' ('-worthiness') of being shared — that's what makes something newsworthy.
