What does one checkmark in WhatsApp signify when sending a message - in detail?

A single checkmark in WhatsApp indicates that your message has been successfully sent from your device to WhatsApp's servers, but it has not yet been delivered to the recipient's phone. This status signifies that your message is currently in transit and awaiting delivery. It does not provide information about whether the recipient has seen or read the message; it merely confirms that your message has left your device and is on its way to the intended recipient. Once the message is successfully delivered to the recipient's phone, you will see two checkmarks indicating that your message has reached its destination.
