Homonym: Diffuse (Spread)
"Diffuse" refers to the process of spreading something out over a larger area. In science, it often describes how particles, such as gases or liquids, move from an area of high concentration to an area of low concentration. This movement continues until the particles are evenly distributed, creating a uniform mixture.
In everyday language, "diffuse" can also mean to make something less intense or to scatter light. For example, a diffuser in lighting helps to soften and spread light evenly, reducing harsh shadows and creating a more pleasant atmosphere.
