Synonym discussion
Sense: noun/2
All four words refer to a dead body, but they differ in context and connotation. 'Mummy' specifically describes a body that has been preserved — either deliberately (as in ancient Egypt) or naturally (by ice, bog, or desert conditions) — and is often wrapped. 'Corpse' is the general term for a dead human body, with no implication of how long it has been dead or how it was treated. 'Remains' is broader and slightly more euphemistic; it can include bones, ashes, or partial body parts found at an archaeological site. 'Cadaver' is a clinical term used mainly in medical and scientific settings for a body donated for dissection or study. For example: 'The archaeologists uncovered the mummy of a priest still wrapped in linen,' but 'The medical students examined a cadaver in the anatomy lab.'
Etymology
The word 'mummy' has two completely separate origins. The mother sense comes from the natural baby-talk sound 'ma' for mother, found in many languages around the world. The preserved body sense traces back through French 'momie' and Latin 'mumia' to Arabic 'mūmiyā', meaning 'embalmed body' — a word that originally referred to bitumen (a type of tar) used in the Egyptian embalming process.
