What is the German word for 'ignition'?

The German word for 'ignition' is "Zündung." This term specifically refers to the act of igniting or starting a fire, particularly in the context of engines, where it denotes the process that initiates combustion.

In automotive terminology, "Zündung" is commonly used to describe the ignition system, which is essential for starting a vehicle. The other terms provided refer to different concepts: "Start" implies the beginning of an action but does not specifically mean ignition. "Entzündung" translates to 'inflammation' or 'inflammation condition,' often relating to medical contexts or other types of reactions rather than the ignition process. "Feuer," meaning 'fire,' is a broader term that encompasses combustion but does not denote the specific mechanism of ignition. Thus, "Zündung" accurately captures the meaning of 'ignition' in both everyday and technical contexts.
