Grüber

gröber is a German adjective used to express a higher degree of coarseness or roughness. It functions as the comparative form of grob and describes something that is less fine, more coarse, or more crude in texture, grain, or manner. The term can apply to physical materials as well as to abstract qualities such as language or behavior.

In standard spelling, gröber is formed with an umlaut and the suffix -er. The word appears in contexts ranging from material description to linguistic or stylistic assessment. Examples include gröber Sand or gröbere Körnung (coarser sand or coarser grain), and gröbere Ausdrucksweise (a cruder way of speaking). The form is typically declined to agree with gender, number, and case in attributive and predicative positions.

Gröber contrasts with the corresponding positive grob (coarse or rough) and the opposite feiner or feinst (finer or more delicate) depending on context. The nuance is not moral or evaluative in itself; it denotes relative roughness, often in technical or comparative descriptions such as geology, construction, or product specifications.

In usage, gröber can refer to tangible properties—such as the texture of a surface or the granularity of a material—as well as to more subjective judgments about style or quality. The term is widely understood in German-speaking contexts and appears in technical writing, everyday language, and descriptive prose.
