Shed light on意思

"Shed light on" is an English idiom that means to provide information or understanding about something that was previously unknown, unclear, or mysterious. The phrase suggests that the new information or understanding illuminates the subject, much like a light shining on a dark area would make it visible.

For example:

"The new evidence shed light on the motives behind the crime." "Her research sheds light on the ancient civilization's way of life." "His testimony shed light on the events leading up to the accident."

In these examples, the evidence, research, and testimony are all providing clarity or insight into previously unknown or unclear aspects.
