Old English deað "death, dying, cause of death," in plura, "ghosts," from Proto-Germanic *dauthaz (cf. Old Saxon doth, Old Frisian dath, Dutch dood, Old High German tod, German Tod, Old Norse dauði, Danish død, Swedish död, Gothic dauþas "death"), from verbal stem *dheu- (3) "to die" (see die (v.)) + *-thuz suffix indicating "act, process, condition."
I would not that death should take me asleep. I would not have him meerly seise me, and onely declare me to be dead, but win me, and overcome me. When I must shipwrack, I would do it in a sea, where mine impotencie might have some excuse; not in a sullen weedy lake, where I could not have so much as exercise for my swimming. [John Donne, letter to Sir Henry Goodere, Sept. 1608]

The death-watch beetle (1660s) inhabits houses, makes a ticking noise like a watch, and was superstitiously supposed to portend death.
FEW ears have escaped the noise of the death-watch, that is, the little clickling sound heard often in many rooms, somewhat resembling that of a watch; and this is conceived to be of an evil omen or prediction of some person's death: wherein notwithstanding there is nothing of rational presage or just cause of terror unto melancholy and meticulous heads. For this noise is made by a little sheathwinged grey insect, found often in wainscot benches and wood-work in the summer. [Browne, "Vulgar Errors"]
The end of life; the permanent cessation of vital bodily functions, as manifested in humans by the loss of heartbeat, the absence of spontaneous breathing, and brain death.
The end of life of an organism or cell. In humans and animals, death is manifested by the permanent cessation of vital organic functions, including the absence of heartbeat, spontaneous breathing, and brain activity. Cells die as a result of external injury or by an orderly, programmed series of self-destructive events known as apoptosis. The most common causes of death for humans in well-developed countries are cardiovascular disease, cancer, Alzheimer's disease, certain chronic diseases such as diabetes and emphysema, lung infections, and accidents. See also brain death.
