defunct
Out of operation
Defunct means no longer existing, functioning, or in use.
A defunct company has ceased operations.
A defunct magazine no longer publishes.
The word often describes institutions or organizations that have formally ended rather than things that simply broke: the defunct Soviet Union, a defunct railroad.
Something defunct isn't just inactive—it's permanently finished.
