Hello Pauline Hanna,
Welcome to Microsoft Community.
Word, Excel, and Outlook are Microsoft Office programs that are not normally included in Windows 11.
But if you want to ask if you buy a Windows 11 device with these Office products pre-installed, the answer is that it depends on whether the seller is willing to give you the relevant Office products.
If the seller only promises that the device will be pre-installed with Windows 11, but it does not come with any Office products, then your device does not have the permission to use Word, Excel, and Outlook, and you need to buy another one.
If the seller indicates that the Office product will come pre-installed on your device, please confirm whether the Office product is a permanent product (such as Office Home & Student 2021) or if you are only giving away a fixed-term subscription to the Microsoft 365 product.
Permanent products typically include Word, Excel, and PowerPoint, but not Outlook(Office Home & Business 2021 includes Outlook)
The Microsoft 365 subscription includes most of the Office suites.
The differences between the products can be confirmed at the following link:
If anything is unclear, please do not hesitate to let me know.
