undead

Etymology

It is formed from English un- + dead, first as undede (“still living, not dead”).^[2][3][4][5] The OED compares Old Norse údauðr.^[2] Old English had undēadlic (“immortal, undying”),^[6][3] which Etymonline compares with undying.^[3]

Earliest recorded meaning

Not dead, alive: in the alliterative Wars of Alexander, composed before 1400 and copied about 1450.^[2][5] Etymonline dates the word to about 1400, meaning "still living, not slain".^[3]

Semantic evolution

In Middle English the word simply meant "not dead".^[2][3] In 1897 it became a noun for vampires and similar beings that are clinically dead but not yet at rest,^[3][7] and that use gave the adjective the sense "neither dead nor alive".^[3][7][2] Dictionary.com dates the modern word to 1895–1900.^[8] The noun is usually collective, the undead, and is also applied to zombies.^[4][7][9]
