unusable
Not fit anymore
Unusable describes something that cannot be used, whether because it's broken, incompatible, or otherwise unfit for purpose: The water damage left the keyboard unusable.
The word often appears in technical contexts—unusable data, unusable code—or to describe things rendered nonfunctional: The bridge was unusable after the flood.
