When dealing with a terrible new software update, you need the right words to express your frustration. In German, you can easily flip the meaning of words to their negative counterparts by attaching the simple prefix un-.
Negating Adjectives
Adding un- to the beginning of a German adjective turns it into its exact opposite, perfectly mirroring how "un-", "im-", or "in-" work in English.
For example, logisch (logical) becomes unlogisch (illogical), and brauchbar (usable) becomes unbrauchbar (unusable).
| The software is completely illogical and unusable! | Die Software ist völlig unlogisch und unbrauchbar! |
Similarly, möglich (possible) flips to unmöglich (impossible), and zufrieden (satisfied) becomes unzufrieden (dissatisfied).
| We became dissatisfied because the system is unusable. | Wir wurden unzufrieden, weil das System unbrauchbar ist. |
Negating Nouns
Unlike in English, where "un-" is mostly reserved for adjectives and verbs, German freely attaches un- directly to nouns.
Sometimes this creates a direct opposite state. For instance, die Zufriedenheit (the satisfaction) becomes die Unzufriedenheit (the dissatisfaction).
| The dissatisfaction outside the department is growing. | Die Unzufriedenheit außerhalb der Abteilung wächst. |
In other cases, adding un- implies a "bad" version of the root noun, or a complete lack of it. Der Sinn (the sense or meaning) turns into der Unsinn (the nonsense), and die Ordnung (the order or tidiness) turns into die Unordnung (the mess or disorder).
| This nonsense makes me angry. | Dieser Unsinn macht mich wütend. |
| The update caused a mess. | Das Update hat eine Unordnung verursacht. |
