der Automat, -en

The German word "Automat" is a noun that means "machine" or "automaton", in the sense of a self-operating machine. Specifically, it refers to vending machines or automated service machines. "Automat" is derived from Greek "automatos" meaning "acting of itself", "self-moving" or "self-willed".

Words in German with a similar meaning might include "Maschine" (machine), although "Maschine" has a broader sense and is not limited to self-operating machines. There is no significant difference in meaning between "Automat" and "Automatik", as the latter simply refers to something that operates automatically, which can be a function or integral part of an "Automat".
