A witness is someone who sees or experiences an event firsthand and can describe what happened. In a courtroom, witnesses take an oath to tell the truth about what they saw or heard, helping judges and juries understand the facts of a case. A witness to a car accident might describe which driver ran the red light. A witness to history lives through important events and can tell future generations what really happened.

The word also means to see something yourself, often something significant or unusual. You might witness a meteor shower, witness your best friend's kindness when they help someone in need, or witness an exciting finish to a championship game. When you witness something, you're present as it unfolds, experiencing it directly with your own eyes and ears.

To bear witness means to testify or provide evidence about something you experienced. Survivors of historical events bear witness to what they lived through, ensuring those stories aren't forgotten.

The word carries weight because a witness has special authority: they were actually there. That's why witnesses matter so much in court, in history, and in understanding the truth. Your own observations as a witness count for something that rumors and guesses never can.
