How it's used

This phrase is a formal idiom that often feels slightly out of place in very casual, rapid-fire conversation. It is frequently used in news reports, formal presentations, or when someone wants to emphasize a point that they believe should be obvious to everyone. Using it in everyday chat can sometimes sound a bit sarcastic or condescending if the listener actually did not know the information.

Common mistake

Learners often mistakenly use this phrase to introduce a new fact they just learned, but it should only be used for information that is already widely accepted or established. It is not a way to introduce a topic, but rather a way to frame a shared truth.
