独身

1. Origins, structure, and basic meaning

• Structure: In 独身 (どくしん), alone 独 and person 身 combine to denote unmarried status.
• Basic usage: 独身で and 独身だ predicate being unmarried.

2. Common pitfalls and similar expressions

• Marital status
  • That status does not necessarily mean living alone or having no partner, so those facts should not be added automatically.
