Boarding is getting on a plane, a ship or a train, and you mostly meet the word in an announcement: boarding will begin at gate twelve in ten minutes. You show your boarding pass, and the queue shuffles forward.
Boarding is also living at a school during term, which is what a boarding school is for, and taking in an animal while its owner is away: kennels and catteries charge for boarding by the night, and the good ones are full by June. Its oldest meaning is plain wood — boarding is boards nailed side by side, on a fence or over a broken window.
