What is the definition of a nomad?

The definition of a nomad refers to individuals or groups who move from one place to another rather than settling permanently in one location. These movements are often driven by the search for resources, such as food, water, and grazing land for livestock. This concept emphasizes the lifestyle of mobility and adaptation to varying environmental conditions, making wandering in search of resources the central characteristic of a nomadic existence.

In contrast to the other options, a permanent home or established community is not applicable to a nomad, as their way of life is inherently characterized by movement and often seasonal migration.
