Translation

下宿人 / 寄宿生 / 寮生

Meaning

A boarder is a person who pays to live in someone's house or at a school, often with meals included. It is about lodging, not a boundary line. Do not confuse it with border.

Examples

• その家族は空き部屋に下宿人を一人受け入れた。
  The family took in a boarder for the spare room.
• 彼は寄宿生としてその学校に通っていた。
  He attended the school as a boarder.
