"Stuff" refers to a broad category of physical items or materials that people use in their daily lives. This can include anything from household goods like furniture and appliances to personal belongings such as clothing and accessories. The term is often used informally to describe a collection of various objects without specifying each one. In a more abstract sense, "stuff" can also refer to non-physical concepts, such as ideas, information, or experiences. For example, one might say they have a lot of "stuff" on their mind, indicating a range of thoughts or concerns. Overall, "stuff" encompasses both tangible and intangible elements that make up our surroundings and experiences.
