/dɪˈfjuːzə(r)//dɪˈfjuːzər/The word "diffuser" has a fascinating origin! It dates back to the 14th century, derived from the Old French word "diffuser," meaning "to scatter" or "to spread." This term was borrowed from the Latin "diffundere," which also conveys the idea of spreading or dispersing something, such as light or heat. Initially, the term was used to describe the act of making something spread or disperse, like the diffusion of liquids or gases. In the 17th century, the term took on a more specific meaning in chemistry, referring to a device that disperses or spreads a substance, such as air, gas, or a fragrance, evenly throughout a space. Today, the word "diffuser" is commonly used in various contexts, including aromatherapy, lighting, and even computer science.
