Etymology: The plural "diffusers" simply pluralizes "diffuser," which is built from the verb "diffuse" plus the suffix "-er," the common English ending for a person or thing that performs an action. The verb "diffuse" comes from Latin "diffundere," meaning "to pour out in different directions," combining "dis-" (apart) with "fundere" (to pour). Its original sense was literal: liquids and gases spreading outward from a source. The noun's modern meaning grew out of that physical image. A diffuser, whether a frosted glass panel softening a lamp or a grille scattering air from a vent, does with light, sound, or air what the verb describes: it takes something concentrated and spreads it out so it reaches every part of a space evenly.
