Magento 2 has a rich in feature to add categories as it comes with default root category. You can create your own category and name as your wish. First and foremost you need to login magento dashboard. Navigate to products > Categories as shown in fig. 1.0
There is already a root category by default. All you need to do is select Default Category and click on Add Subcategory as shown in fig : 1.1
