testify

To testify is to share your personal experience or knowledge with others, often in a formal setting like court.

Think of it like telling the truth about what happened. When you testify, you're giving your side of the story and speaking from your own understanding. This can be a bit nerve-wracking, but it's an important way to help clarify things for others or provide evidence. People might testify in court as witnesses, sharing what they saw or heard. They could also testify about something they've studied or learned, like a scientist explaining their research findings.
