What does news really mean? Is it a plural word of "new"?
Answer from a Native speaker
"News" is not the plural form of the adjective "new." It's a noun, meaning recent or unreported information, such as about recent events. "Bad news" means sharing or reporting about an unhappy or unfortunate event or incident. Contrastingly, "good news" is the reporting of a happy, fortunate incident. Ex: Did you see the news? There was an accident near our house. Ex: The husband got fired from his job. He didn't know how to tell his family the bad news. => He didn't know how to tell his family about the unfortunate incident. Ex: I have something to tell you. It's good news! => It's something good.
