What does undead mean?
Undead refers to a person, creature, or spirit that is dead but nevertheless remains active, conscious, or able to return to life. In modern fantasy and horror, it usually means a reanimated corpse, though it can also cover skeletons, ghosts, and other beings presented as dead yet not at rest. The word is used both adjectivally, as in an undead king, and as a noun, most often collectively. Its power comes from the tension it creates between two opposites: the body is no longer alive, but it refuses the finality of death. As a result, undead carries strong associations with horror, pursuit, decay, and ancient threats rather than neutral biological description. Outside fictional and game-related contexts, it is usually figurative or deliberately sensational, describing something old, persistent, or impossible to kill. Even in such uses, it implies more than mere death: something dead has continued to act.
Dead yet animate, conscious, or active; belonging to or characteristic of such a being.
"An undead army approached the walls beneath a blood-red moon."
Commonly used before nouns such as king, army, creature, and horror.
A dead person, creature, or spirit that has been restored to life or remains capable of thought and action.

Frequently used collectively; the plural is normally unchanged.
The standard plural and collective form is unchanged, as in the undead. The singular an undead is also possible but is less common, while undeads is uncommon.

Death supplies the body, but something keeps it moving: that is the enduring menace of the undead.
