vagrant
A person who wanders without a permanent home or job.
A vagrant is a person who wanders from place to place without a permanent home or regular job. Historically, the word often appeared in old laws about vagrancy, which made it illegal to live without visible means of support. In the 1800s and early 1900s, police could arrest vagrants simply for not having a fixed address or steady employment.
The word carries a somewhat negative tone, suggesting aimless drifting rather than purposeful travel. A backpacker exploring Europe has a plan and resources, while a vagrant wanders without clear direction or stability. You might encounter this word in classic literature: in The Adventures of Huckleberry Finn, characters sometimes worry about being mistaken for vagrants.
Today we more commonly use words like person experiencing homelessness when talking about people without permanent shelter, as vagrant can sound old-fashioned and judgmental. The word shows how society's attitudes toward poverty and homelessness have changed over time. What once was often treated as a crime is now more widely seen as a complex social problem that many people believe should be met with compassion and practical help.
