What does hilliness mean?
Hilliness is a noun meaning the state or quality of being hilly. It refers to the presence of frequent elevations and uneven ground, particularly in a landscape. The word can describe a place's visible topography, as when writers note the hilliness of a region, or its practical effects, such as making walking, cycling, or travel more demanding. It is more formal and less common than the adjective hilly, but it is useful when a noun is needed or when the quality of the terrain itself is being emphasized. Hilliness does not necessarily imply steep slopes; it primarily suggests that the land has many rises or hills. In careful writing, it is best reserved for geographic descriptions, where it conveys the physical shape and character of the landscape.

Hilliness names a landscape's characteristic rise and fall: even a modest elevation can make a place surprisingly demanding to travel across.
