lodger
tenant / boarder / guest
Noun
pl: lodgers
This term describes a residential arrangement where the tenant lives within the primary residence of the landlord, often sharing common areas. It carries a connotation of domestic intimacy and a less formal legal relationship than a standard apartment lease. In a commercial context, such as an inn or boarding house, the term refers to a temporary guest who occupies a room. This usage emphasizes the transient nature of the stay compared to the long-term residential lodger.
