What do two brackets mean in a WhatsApp conversation - in detail?

In the context of WhatsApp conversations, two brackets are commonly used to indicate that a message has been forwarded from another source or chat. This feature allows users to see when a message has not been originally created by the person who sent it to them. When a user forwards a message, WhatsApp automatically adds two brackets around the text to signify its origin. This is particularly useful in situations where misinformation or fake news might be circulating, as it enables recipients to verify the source of the information and assess its credibility more critically. Additionally, it promotes transparency within conversations, making it clear when content has been shared from elsewhere.
