Origin
The term "deathrattle" has been used for centuries to describe the sound that accompanies the dying process. It is mentioned in various historical texts, including:
The Anglo-Saxon Chronicle (10th century): "And siððan him wearð swa swiðe yfele þæt him com deáðhreðe ðurh þone múð." (And then he grew so ill that the death-rattle came from his mouth.)
The Canterbury Tales by Geoffrey Chaucer (14th century): "His mouth gaped, and his eyen stared; / He groneth in his throte, as a sparwe departed."
The Journal of the Plague Year by Daniel Defoe (1722): "They would be seized with violent pains all over, and a faintness and trembling in the limbs; and presently after, the death-rattle in the throat."
Over time, the term "deathrattle" has become synonymous with the end-of-life process and the inevitable fate that all living beings must face.
