constructible
Able to build
Constructible describes something capable of being constructed or built.
In everyday use, it applies to physical structures: The architect confirmed the design was constructible within budget.
In mathematics, particularly geometry, constructible refers to figures that can be drawn using only a compass and straightedge—a circle is constructible, but trisecting an arbitrary angle is not.
Also spelled constructable.
