What is the primary function of dovetail joinery in drawers?

• A. They are decorative only and do not contribute to structure.
• B. They are the simplest form of joint.
• C. Dovetails interlock to resist pulling apart, providing strong, long-lasting drawer sides.
• D. They are used only in table legs.

Answer: (C)

Dovetail joints create an interlocking system of tails and pins that resists being pulled apart, which is exactly what a drawer encounters when it’s opened and the front edge is tugged outward. That mechanical lock transfers the pulling forces along the joint, keeping the sides from loosening or separating over time, so the drawer remains sturdy and durable even with heavy use. They’re more than decorative; they’re chosen specifically for the way they resist lift-out and shear forces, unlike simpler joints or joints used in other parts of furniture. This is why they’re a classic choice for drawer construction, providing long-lasting strength where the most stress occurs.
