What does comatose mean?
Comatose describes a person who is in a coma — a state of deep, sustained unconsciousness from which they cannot be awakened, even by strong stimulation. It is most often used in medical and journalistic contexts, as when an accident victim is reported to be comatose following a head injury, stroke, or drug overdose. The term carries serious, clinical connotations in this sense, signaling a grave condition requiring intensive care. Beyond medicine, comatose has developed a vivid figurative use: anything remarkably sluggish, listless, or unresponsive can be described as comatose, from a drowsy afternoon audience to a stagnant economy. This extended sense is informal and frequently ironic or humorous. Derived from the Greek word for deep sleep, the adjective pairs naturally with terms like state, patient, and condition, and it remains one of the most precise single words available for total, unrousable unconsciousness.
adjectiveIn a state of profound unconsciousness from which one cannot be roused, typically caused by severe illness, injury, or intoxication; by extension, extremely lethargic or inactive.
- Medicine: in a state of deep, prolonged unconsciousness from which the person cannot be awakened.
- Figurative/informal: extremely drowsy, sluggish, or inert, as if half-asleep.
"After the accident, he remained comatose for three weeks before slowly regaining consciousness."
"The boxer was left comatose after the brutal final round."
"By mid-afternoon the office felt comatose, everyone slumped over their desks."
The word comes from the Greek 'kōma', meaning 'deep sleep' — ancient physicians literally thought of coma as a sleep so deep it bordered on death.

Etymology of comatose
Comatose derives ultimately from the Greek noun kōma, meaning 'deep sleep' or 'trance'. Medical Latin adopted the term, and the adjective comatose was formed in New Latin before entering English in the mid-17th century, when physicians used it to describe patients sunk in pathological sleep. Its only close relative in modern English is the noun coma, which shares the same Greek root; both words preserve the original image of sleep so profound it resembles death.
How comatose is actually used
The medical sense is formal and clinical, common in news reports and hospital settings; the figurative sense ('comatose economy', 'comatose crowd') is informal and often humorous or critical, implying lifeless inactivity rather than literal unconsciousness.
