boarder

The student body consisted primarily of boarders, except for a few children belonging to the school staff.

When I left for college, my parents took on a boarder in my old room to help defray expenses.

I have found holding all doors open solves much of this problem, as late boarders can enter the rear and tag in rather than wait the time it takes to get to the front, particularly if the bus shelter or some other obstacle hinders vision and boarding.

The captain shouted at the crew to grab arms and repel boarders.

A group of boarders swept past us as we climbed the side of the ski run.
