I think the greatest thing about the German language is its practicality. "Ausgang" or "exit", literally from the words 'go out' or 'gone out' but that describes the action and noun. It is the description of the word that becomes the word. "Escalator" is "Fahrtreppe" or "Rolltreppe", literally moving/going stairs or roll stairs.

w.r.t exit, that's just because english borrowed the word from another language:

From exeō ‎(“exit, go out”), from ē ‎(“out”) + eō ‎(“go”).
