Etymology
The word "air-source" is a fairly straightforward compound word, meaning it's made by combining two existing words: "air" and "source."
Air: This word has very old roots, coming from the Middle English word "air," which itself was borrowed from the Old French word "air." Ultimately, it traces back to Latin "āēr" and Greek "ἀήρ," both referring to the atmosphere or the invisible substance we breathe. Its meaning has remained consistent over centuries.
Source: This word comes from the Old French word "sourse," meaning "a spring, fountain, or origin." It refers to the point from which something comes or begins.
When you put them together as "air-source," the meaning becomes quite literal: something that uses "air" as its "source."
The first known use of "air-source" as an adjective, specifically in relation to technology like heat pumps, appears to be in the 1940s. The Oxford English Dictionary (OED) notes its earliest evidence from 1948, found in Architectural Record. At that time, its meaning would have been exactly what we understand today: referring to systems or devices that draw their energy or primary material from the ambient air, particularly in the context of heating and cooling.
