Picture a short list of grades written from the top down: first class, second class, third class. Third class is the bottom step of that list. Whatever is being — a seat on a train, a bag of post, a university degree — the words only say where it sits: at the bottom, cheapest, lowest. That is why the same two words can name a hard wooden seat, a pile of advertising and a degree certificate without changing their meaning.

The cheapest and least comfortable part of a train or a ship, below first class and second class. On British trains and ships long ago it meant hard seats and crowded space, and in some countries third-class tickets are still sold today.
