Frequently Asked Questions

It is highly unlikely you would need to, unless you are specifically discussing furniture design or woodworking techniques. It is a very low-frequency technical term.
Its main purpose is functional and aesthetic: to allow a part of furniture (like a table leaf) to fold down neatly while maintaining a continuous, unbroken surface line when upright.
No, the etymology is unclear but is thought to possibly relate to the joint allowing a 'ruled' or straight line, or from an old tool called a 'joint rule'. It does not refer to a regulation.
