Ship
From Tardis Wiki, the free Doctor Who reference
Ship was a word which could refer to a boat (PROSE: No Room) or a spacecraft.
The First Doctor described the TARDIS as a ship and would refer to it as "the ship". (TV: An Unearthly Child) Meeting the First Doctor just prior to his regeneration, the Twelfth Doctor was amused to hear him still referring to the TARDIS as such. (TV: Twice Upon a Time)
