What is the German word for 'glue'?

The German word for 'glue' is "Klebstoff." This term is widely used in both everyday language and technical contexts to describe adhesive substances used for bonding various materials together. "Klebstoff" directly translates to "glue" in English and combines the words "kleben," meaning "to stick," and "Stoff," meaning "substance."

The other choices, while related to adhesives, do not serve as the standard term for 'glue.' "Adhesiv" is more of a technical term borrowed from English, often used in specific fields rather than in everyday conversation. "Band" translates to "band" or "strip," which might refer to adhesive strips but does not mean glue itself. "Kleber" can also refer to a type of adhesive, particularly in a more informal context, but "Klebstoff" is the widely accepted term for glue in German.
