duallike

Duallike is an adjective used to describe phenomena, objects, or ideas that exhibit two distinct yet interrelated facets, often functioning as a pair rather than as a single property. The term is used in fields such as philosophy, cognitive science, physics, and design to emphasize dual aspects that can be simultaneously present or contextually alternating. It is formed from dual and like and is more common in niche or informal discourse than as a standardized technical term.

In philosophy and metaphysics, duallike describes positions that treat mind and body, or form and matter, as two interdependent aspects of reality rather than as reducible to one another. In physics, the phrase is sometimes used informally to characterize wave–particle duality, where entities such as light or electrons display both wave-like and particle-like behavior depending on the experiment. In design and computing, duallike may describe interfaces or systems that support two coherent modes—for example, a device that can switch between editing and presentation modes, or data schemas that support dual interpretations (relational versus graph).

Because it is not a standardized term, its exact meaning is highly contextual and dependent on the discourse in which it appears. See also duality, ambivalence, bimodality, and dual-use. In short, duallike signals a structured dependency between two facets that are simultaneously salient or alternately active.
