* Sett: This is the general term for the complex underground burrow system that badgers live in.
* Holt: This is a more specific term for a badger sett, often used in older texts or in certain regions.
* Earth: This is a broader term for any burrow or underground dwelling, but it's often used to refer to a badger sett.
So, while all three terms are used to describe badger homes, "sett" is the most common and accurate term.
