1. Stiff; not pliant; not easily bent. It is applied to bodies or substances that are naturally soft or flexible, but not fluid. We never say, a rigid stone or rigid iron, nor do we say, rigid ice; but we say, an animal body or limb, when cold, is rigid. Rigid is then opposed to flexible, but expresses less than inflexible.
