How do you say 'scratch' in German?

The term for 'scratch' in German is indeed 'Kratzer.' This word is used to describe a mark or abrasion made on a surface, which aligns closely with the English term. In everyday usage, you might refer to a 'Kratzer' when talking about a scratch on a car, furniture, or even on skin.

The other options do not accurately translate to 'scratch.' For instance, 'Schraube' means 'screw,' which is a completely different concept. 'Rauheit' translates to 'roughness,' which relates to texture rather than a scratch itself. Lastly, 'Dichtung' means 'seal' or 'gasket,' making it unrelated to the idea of a scratch. Therefore, 'Kratzer' is the appropriate choice for 'scratch' in German.
