adjective / noun / adverb
dead
DED/ded/
No longer possessing life or activity.
The dead plant has collapsed brown leaves and a brittle stem.

Etymology
Old English dead already covered both having ceased to live and being torpid or dull. This broader association with inactivity connects literal death to the description of something that no longer functions.
In context
All through the winter the dead rotted by the wayside for want of some one to bury them. In many a village no single man was left alive.
