What word best describes someone who travels frequently without settling in one place?

The term that best describes someone who travels frequently without establishing a permanent home is "nomad." This word is derived from historical contexts in which groups of people moved from one place to another in search of resources, rather than settling down in one location. Nomads often adapt to different environments and cultures as they travel, emphasizing mobility and a lifestyle that does not rely on permanent structures or communities.

In contrast, a "settler" refers to a person who moves to a new area to establish a permanent home, which directly opposes the idea of frequent travel without settling. A "citizen" is someone who legally belongs to a particular country or community, often implying a stable lifestyle associated with a specific location. Similarly, a "resident" denotes someone who lives in a particular place for an extended period, emphasizing permanence rather than the movement characteristic of nomadic individuals. Thus, "nomad" accurately captures the essence of a person who frequently travels without settling down.
