Welcome to the mystical apothecary. To brew potions, you need to know how to ask for exact quantities of magical ingredients. Let's look at how to say "a pinch of ash" or "a drop of potion" in German.
Partitive Apposition: Basic Quantities
In English, we connect a quantity and a material with the word "of" (for example, "a gram of herb").
When you talk about a general, unmodified material in German, you do not use a word for "of". Instead, you simply place the quantity noun and the material noun right next to each other. This grammatical structure is called an apposition.
The Partitive Genitive: Specific or Modified Materials
If the material is not just a general substance, but has a descriptive word attached to it—such as a definite article, a demonstrative (dieser), or an adjective—German switches to the Genitive case.
The genitive case takes over the job of showing "of the" or "of this". Notice how masculine and neuter material nouns will add an -s or -es to their endings.
When an adjective modifies a masculine or neuter material directly (without an article in front of it), the noun still takes its genitive -s or -es, and the adjective usually takes an -en ending.
Side-by-Side Comparison
To master gathering your ingredients, pay close attention to whether the material is modified or standing alone. Compare these final examples, noticing when the genitive is triggered by an adjective or a word like dieses, and when the nouns remain a simple apposition.
