To delete a contact from WhatsApp, you'll need to remove them from your phone's contact list. Here's how you can do it:
1. *Open your Contacts app:* Navigate to the Contacts app on your phone. This app may have different names depending on your device and operating system (e.g., Contacts, People, Address Book).
2. *Find the contact you want to delete:* Scroll through your contacts list or use the search function to find the contact you want to remove from WhatsApp.
3. *Select the contact:* Tap on the contact to open their details.
4. *Open the menu:* Depending on your device, there may be a menu icon (usually three dots) in the top right corner of the screen. Tap on this icon to open the contact options menu.
5. *Choose "Delete" or "Remove":* From the contact options menu, select the option that says "Delete" or "Remove." You may be asked to confirm the deletion.
6. *Confirm the deletion:* If prompted, confirm that you want to delete the contact. The contact will then be removed from your phone's contact list.
Once you've deleted the contact from your phone's contacts, they will also be removed from your WhatsApp contacts list. If you had any existing chats with that contact in WhatsApp, the chat history will still be visible on your phone, but their name will appear as a phone number (without a profile picture or name).
