Etymology
The word "infill" is a transparent modern English compound, formed by combining the native prefix "in-" with the verb "fill". Its construction follows a straightforward Germanic pattern where a prepositional prefix modifies the action of the root verb, literally meaning "to fill in". Initially used in general contexts for the act of filling a cavity, its specialized meaning in urban planning emerged in the mid-20th century. This term describes the practice of developing vacant plots within already built-up areas, logically extending the core idea of putting something into an empty space to the urban landscape.
