What does aerophore mean?
An aerophere is a device designed to supply air for breathing, most famously as a portable reservoir of compressed air worn by divers working underwater. The term derives from the Greek roots 'aer' (air) and 'pherein' (to carry), so it is literally an 'air-carrier'. In the history of diving, aerophores were among the earliest self-contained breathing systems, predating the modern scuba regulator that eventually replaced them in common use. Beyond diving, the word has also been applied to certain medical devices that deliver air or medicated vapour to patients. Today 'aerophore' is a relatively rare, technical term, encountered chiefly in historical writing about diving technology and in specialized medical contexts. Its decline in everyday use reflects the success of newer terms like 'scuba' and 'breathing apparatus', but it remains a useful word for anyone reading nineteenth- and early twentieth-century accounts of underwater exploration.
nounAn aerophore is a device that supplies air for breathing, especially a portable apparatus of compressed air used by divers underwater.
- A portable apparatus supplying compressed air for breathing underwater, used by divers.
- Any device for conveying or supplying air, including medical inhalation devices.
"The early diver descended with an aerophore strapped to his back, its compressed air sustaining him far below the surface."
"The salvage crew tested each aerophore carefully before allowing the divers into the wreck site."
"In the hospital ward, patients relied on a small aerophore to deliver medicated air directly to the lungs."
Standard English plural, formed by adding -s.
"The museum displayed several early aerophores alongside modern diving equipment."
Before the word 'scuba' existed, divers called their life-support gear an aerophore — literally an 'air-carrier'.

Etymology of aerophore
The word aerophore comes from the Greek 'aer' meaning air and 'pherein' meaning to bear or carry, giving the literal sense of something that carries air. It was formed on this classical pattern during the nineteenth century, when inventors were developing apparatus for breathing underwater. The same Greek combining elements appear in many English words: 'aer' surfaces in aeroplane and aerate, while '-phore' appears in semaphore and phosphorus-related vocabulary. As diving technology evolved, the term was gradually displaced by later coinages such as 'scuba'.
How aerophore is actually used
A technical and somewhat dated term, now largely superseded by 'scuba' or 'breathing apparatus' in everyday diving contexts. It survives mainly in historical accounts of diving and in some medical equipment terminology.
Easily confused with aerophore
An aerator introduces air into a substance such as water or soil, whereas an aerophore is a wearable or portable device that supplies breathable air to a person.
