A more thorough explanation:

Approach the witness

Approach the witness means when a lawyer moves towards a witness to show them a document or exhibit. In some places, the lawyer must ask for permission to approach the witness by saying "may I approach the witness?"

During a trial, the lawyer may approach the witness to show them a picture of the crime scene or a piece of evidence. The lawyer may also approach the witness to ask them a question that is not audible to the judge or jury.

For instance, if a witness is hard of hearing, the lawyer may need to approach them to speak louder or more clearly. This way, the witness can understand the question and provide an accurate answer.

Another example is when a lawyer wants to show a document to the witness. The lawyer may approach the witness and hand them the document to review. This way, the witness can confirm or deny the information in the document.

These examples illustrate how approaching the witness is a common practice in courtrooms. It allows lawyers to communicate with witnesses effectively and present evidence clearly.
