A single checkmark in WhatsApp indicates that your message has been sent from your device but not yet delivered to the recipient's phone. It means the message is still in transit and has not been received by the intended user.

What does a single checkmark mean in WhatsApp - in detail?

A single checkmark in WhatsApp is a fundamental indicator of the status of your message. When you send a message and see only one checkmark next to it, it means that WhatsApp has successfully delivered your message to the recipient's device. However, this does not guarantee that the recipient has read or even seen your message. The single checkmark is simply an acknowledgment that your message has reached its intended destination, but beyond that, no further action has been taken by the recipient. This status allows users to understand that their communication has been successfully transmitted, yet provides no information regarding whether the recipient has interacted with it.
