When evaluating futuristic gadgets—like holograms, drones, and invisible chips—you might not always know exactly what you are looking at. Is it "something interesting"? Or just "a lot of useless stuff"?
Something Interesting
In English, we use phrases like "something useful" or "nothing bad" to talk about abstract ideas. In German, you create these abstract concepts by pairing an indefinite pronoun—like etwas (something), nichts (nothing), or viel (much / a lot)—with an adjective.
To do this, you turn the adjective into a neuter noun: capitalize it and add the ending -es.
| The hologram shows something interesting. | Das Hologramm zeigt etwas Interessantes. |
Here, the adjective interessant becomes the abstract noun Interessantes. This works exactly the same way with nützlich (useful) when figuring out how to control your new tech:
| We need something useful to control the drone. | Wir brauchen etwas Nützliches, um die Drohne zu steuern. |
Nothing and A Lot
You apply the exact same rule after nichts and viel. Just capitalize the adjective and add -es to describe the abstract things someone is inventing or doing.
| The engineer invents a lot of useless things. | Der Ingenieur erfindet viel Sinnloses. |
| The robot does nothing bad. | Der Roboter tut nichts Schlechtes. |
Regular Adjectives
Keep in mind that this capitalization and -es ending only happen when turning the adjective into an abstract noun. If you are just describing a noun normally using a predicate adjective (an adjective that comes after a verb like "is" or "are"), the adjective stays lowercase and takes no ending:
| The chip is almost invisible. | Der Chip ist fast unsichtbar. |
