Do you say bad news or a bad news

In English, both "bad news" and "a bad news" are grammatically correct, but they have slightly different meanings and uses.

"Bad news" is a noun phrase that refers to information that is unpleasant, unwanted, or disturbing. It's often used to describe a situation or event that has a negative impact.

Example sentences:

• I've got some bad news: the project has been cancelled.
• The doctor delivered some bad news: the patient's condition is terminal.

"A bad news" is not a common phrase in English, and it's not typically used in formal writing or speech. However, if you were to use it, it would imply that "news" is a singular noun, which is not the case.

If you want to convey that you're about to share some unpleasant information, it's generally better to use "bad news" (without the article "a"). This phrase is more idiomatic and widely understood.

So, to summarize:

• Use "bad news" to refer to unpleasant information or a situation.
• Avoid using "a bad news" unless you're speaking informally or in a specific context where it's clear what you mean.
