dovetailshaped

Dovetail-shaped is an adjective used to describe an object or profile that resembles a dove’s tail. In practical terms, it refers to a wedge-like, trapezoidal cross-section with two angled sides that widen or narrow toward one end, creating a notch or projection designed to fit with a matching counterpart. The defining feature is the interlocking potential of the paired shapes, which helps resist separation under load.

The term is most commonly encountered in woodworking and cabinetry through the dovetail joint. In this context, pieces of wood are cut so that one portion forms a “tail” and the mating piece forms a corresponding “pin,” producing an interlocking connection that is strong in tension and resistant to being pulled apart. Variations exist in the exact angles and proportions, but the characteristic interlocking profile remains central.

Beyond wood joints, dovetail-shaped profiles are used in mechanical design for dovetail slots, guideways, and mounting features. Such shapes enable precise alignment and easy assembly while providing mutual restraint against lateral or pulling forces. Dovetail shapes may also appear in components that require repeatable positioning or self-centering behavior, often leveraging the inherent geometry to improve stability.

Etymology derives from the resemblance to a dove’s tail, with the term historically associated with carpentry and joinery. Today, the descriptor is applied more broadly to any profile that imitates this characteristic trapezoidal taper. See also dovetail joint and dovetail slot.
