Literally: “fire thing” / meaning: cigarette lighter
The German language seems to have an obscure obsession with “things”. Or put another way, you can describe virtually any type of device by combine the word Zeug (“thing”, “stuff”) with the actual purpose of the object – for instance, making fire like a Feuerzeug.
Toys are referred to as Spielzeuge (“play things”), tools are Werkzeuge (“work things”), sweets are Naschzeug (“snack things”), vegetables can be referred to as Grünzeug (“green things”).
However, by far my favorite examples of the bunch are vehicles and airplanes which—you might have guessed it—are called Fahrzeuge (“drive things”) and Flugzeuge (“fly things”).
