The term "urban" can refer to both a physical entity and a quality, and there is often some overlap between the two.

The urban as a physical entity typically refers to the built environment of cities and towns, including the buildings, infrastructure, public spaces, and other features that make up the urban landscape. This includes things like skyscrapers, streets, parks, public transportation systems, and other features that are associated with densely populated areas.

The urban as a quality, on the other hand, typically refers to the social, cultural, and economic characteristics of urban areas. This includes things like the diversity of the population, the vibrancy of the local arts and cultural scene, the availability of job opportunities, and the level of social connectedness and engagement among residents.

While there is some overlap between these two definitions, they represent distinct aspects of urban life. The physical entity of the urban landscape can shape and influence the quality of life in an urban area, but it is not the only factor that determines it. Similarly, the quality of urban life can influence the development and evolution of the physical urban landscape, but it is not the only factor that shapes it.
