furniture

This word describes the collective array of functional objects that populate a room. It carries a sense of stability and domesticity, evoking the physical layout and utility of a living space rather than the individual items themselves. Because it is a mass noun, it functions as a conceptual category. You cannot refer to a single piece of furniture as a furniture; instead, you must use a counter like piece or item to isolate a specific object, which distinguishes it from words like chair or table.
