n. the process of becoming or making something cooler
adj. causing a reduction in temperature
The word "cooling" derives from the Old English "cōlian," meaning "to lose warmth," which evolved into "cool" in Middle English, retaining its core meaning of moderate coldness. The suffix "-ing" was added to form a noun or adjective, indicating the action or result of making something cooler. This logical combination reflects the word's straightforward evolution from describing a state to describing a process.
