Prevented from acting, by condition or by design. Of a control switched off, or a body a world was not built for.
Latin dis- (negation) plus habilis (able, apt), from habere (to hold); of a control switched off, or of a body a world was not built for, the same negation applied to two very different things.
Prevented from acting, whether by a switch someone threw or by a world that never accounted for a body. The word is the same for both, and this house is careful about which one it means.
