解説 logisch in your Level:

At the A1 level, 'logisch' is most commonly used as a simple response or a very basic description. You might learn it as a synonym for 'klar' (clear) or 'natürlich' (natural) in very simple contexts. For example, if someone asks 'Do you eat when you are hungry?' you might say 'Ja, das ist logisch.' It is one of those international words that English speakers can easily recognize, making it an 'easy win' for your early vocabulary. You don't need to worry about complex grammar; just use it to agree with obvious statements. It helps you sound more natural in conversation without needing long sentences. Think of it as a more sophisticated version of 'Ja.'

At A2, you start using 'logisch' to connect simple ideas. You might use it in sentences like 'Es ist logisch, dass wir im Winter Jacken tragen' (It is logical that we wear jackets in winter). You are beginning to understand that 'logisch' describes a relationship between two facts. You will also encounter the word in simple reading texts about daily routines or basic science. You should also start noticing the difference between using it as a standalone exclamation ('Logisch!') and using it within a sentence. It's a great word to help you explain 'why' something is the way it is in a very simple way, often paired with 'weil' (because) or 'denn' (for/because).

At the B1 level, you are expected to use 'logisch' to structure your arguments during the speaking and writing parts of your exams. You should be able to describe a 'logische Abfolge' (logical sequence) of events. You might say, 'Zuerst müssen wir das Problem analysieren, dann eine Lösung finden; das ist der logische Weg.' You also start to use the word to critique ideas, perhaps saying 'Das ist nicht ganz logisch' when you disagree with a point in a discussion. At this stage, you should be comfortable with adjective endings, like 'ein logischer Grund' or 'eine logische Entscheidung.' You are moving beyond simple 'yes/no' logic into the realm of structured reasoning.

At B2, 'logisch' becomes a tool for nuanced debate and abstract thinking. You will use it to discuss complex topics like politics, environment, or technology. You might talk about 'logische Schlussfolgerungen' (logical conclusions) or the 'Logik hinter einer Strategie' (logic behind a strategy). You should be able to distinguish 'logisch' from similar words like 'plausibel' (plausible) or 'nachvollziehbar' (comprehensible). In your writing, you use 'logisch' to create cohesion between paragraphs. For example, 'Logischerweise folgt daraus, dass...' (Logically, it follows that...). You are now using the word not just to describe facts, but to build a persuasive case in professional or academic settings.

At the C1 level, you use 'logisch' with high precision. You understand its philosophical roots and can use it in academic contexts. You might discuss the 'formallogische Korrektheit' (formal-logical correctness) of a thesis. You are also aware of the rhetorical power of the word—how calling something 'logisch' can be a way to shut down opposition by claiming your view is the only rational one. You use it in complex structures, such as 'Es entbehrt jeder Logik' (It defies all logic). Your vocabulary includes many related terms like 'logizistisch,' 'unlogisch,' and 'pseudologisch.' You can follow high-level lectures where 'logisch' is used to define the boundaries of a scientific field or a legal argument.

At the C2 level, you have a native-like grasp of the word's every nuance. You can use 'logisch' sarcastically, humorously, or with profound intellectual depth. You might engage in discussions about 'logischer Positivismus' or the limits of logic in human emotion. You can use the word to dissect the subtle structures of literature or complex legal codes. You know exactly when to use 'logisch' versus 'stringent' or 'kohärent.' Your use of the word is effortless, whether you are writing a philosophical essay or engaging in a rapid-fire colloquial debate. You understand that 'logisch' is not just a word, but a reflection of a worldview that prizes clarity and reason above all else.

logisch 30秒で

Logisch means logical or making sense. It is used to describe thoughts, arguments, and sequences that follow a clear, rational order without contradictions.
In casual conversation, Germans use 'Logisch!' as an exclamation to mean 'Of course!' or 'Obviously!', similar to how 'Duh' is used in English.
The word can function as an adjective (a logical step) or an adverb (to think logically), requiring correct endings when placed before a noun.
Commonly paired with 'Schlussfolgerung' (conclusion) or 'Konsequenz' (consequence), it is essential for clear, structured communication in professional and academic German.

The German adjective logisch is a cornerstone of rational communication, deeply rooted in the Greek word 'logos,' which pertains to reason, word, and order. At its core, it describes something that follows the strict rules of logic or formal argumentation. However, in the everyday life of a German speaker, its utility extends far beyond the confines of a philosophy lecture or a mathematics textbook. When you use this word, you are essentially telling your listener that a thought, an action, or a conclusion is coherent, predictable, and based on sound reasoning. It implies that given the premises provided, no other conclusion could reasonably be reached. This makes it a powerful tool for validation in conversations.

Formal Logic: In academic or scientific contexts, it refers to the structural validity of an argument. If the premises are true and the derivation is correct, the result is considered logisch.
Everyday Reasoning: In casual conversation, it often means 'obvious' or 'making sense.' If someone explains why they took a specific route to avoid traffic, you might respond with 'Das ist logisch,' indicating you follow their train of thought perfectly.

Es hat geregnet, also ist die Straße nass. Das ist logisch.

Culturally, Germans value 'Sachlichkeit' (objectivity) and 'Struktur' (structure). Therefore, being called 'unlogisch' (illogical) can sometimes be perceived as a slight critique of one's thinking process. Conversely, presenting a 'logische Schlussfolgerung' (logical conclusion) is the gold standard in German professional environments. You will hear it in meetings, in schools, and even in mundane debates about where to eat dinner. It bridges the gap between cold, hard facts and the intuitive feeling that something just 'clicks' together correctly.

Furthermore, the word is used to describe sequences. A 'logische Abfolge' is a sequence where each step leads naturally to the next. In software development or engineering—fields where Germany has a strong presence—everything must be logisch for the system to function. If there is a 'Logikfehler' (logic error), the entire structure collapses. This emphasis on logical consistency is a defining trait of the language and the cultural mindset it reflects.

Deine Argumentation ist nicht ganz logisch, da du wichtige Fakten ignorierst.

The 'Duh' Factor: When used as an exclamation, 'Logisch!' carries a slightly informal, sometimes sarcastic tone, suggesting that the answer was so obvious it barely needed asking.

Using logisch correctly requires understanding its role as both an attributive and a predicative adjective. As a predicative adjective (following verbs like 'sein' or 'bleiben'), it remains undeclined. For example, 'Die Entscheidung war logisch' (The decision was logical). In this position, it describes the state or quality of the subject directly. However, when used before a noun, it must take the appropriate adjective endings based on gender, case, and number.

Wir suchen nach einer logischen Lösung für dieses Problem.

One of the most common sentence patterns involves the 'wenn... dann...' (if... then...) construction. German speakers often evaluate the validity of these conditional sentences by stating whether the result is 'logisch.' For instance, 'Wenn du nicht lernst, wirst du die Prüfung nicht bestehen. Das ist doch logisch!' This reinforces the cause-and-effect relationship that is central to the word's meaning.

Attributive Usage: Ein logischer Schritt (A logical step), eine logische Konsequenz (a logical consequence), ein logisches Argument (a logical argument).

In more complex sentence structures, you might find 'logisch' paired with modal particles like 'doch' or 'halt' to add emphasis. 'Das ist doch logisch!' translates roughly to 'But that's logical!' or 'That's obviously the case!' The particle 'doch' here serves to point out something that the speaker feels the listener should already know or find obvious. This is a very common way to sound more like a native speaker.

Es ist nur logisch, dass wir jetzt handeln müssen.

When comparing two things, you can use 'logischer' (more logical) or 'am logischsten' (most logical). For example, 'Plan B scheint mir logischer als Plan A.' This comparison is frequently used in business strategy or scientific discussions where multiple hypotheses are being weighed against each other.

You will encounter logisch in a variety of environments, ranging from the highly intellectual to the completely mundane. In the German education system, from 'Gymnasium' to university, 'logisches Denken' (logical thinking) is a highly praised skill. Teachers will often ask students if a certain mathematical proof or historical analysis is 'logisch aufgebaut' (logically structured). If you are listening to a German podcast about science, technology, or philosophy, the word will appear frequently as experts dissect complex theories.

In der Informatik ist alles logisch aufgebaut; es gibt keinen Platz für Zufall.

In the workplace, particularly in fields like engineering, law, and medicine, the term is indispensable. During a 'Besprechung' (meeting), a colleague might critique a proposal by saying, 'Das klingt zwar gut, ist aber nicht ganz logisch.' This is a polite but firm way of saying there is a flaw in the reasoning. Conversely, a boss might praise a report for its 'logische Struktur.' It is also a staple in the world of German detective novels (Krimis) and TV shows like 'Tatort,' where investigators must find the 'logische Verbindung' between clues.

The Colloquial 'Logisch!': If you ask a friend, 'Kommst du heute Abend mit?' (Are you coming tonight?), they might simply reply, 'Logisch!' This is synonymous with 'Klar!' or 'Sicher!'

Even in advertisements, the word is used to appeal to the consumer's sense of reason. 'Die logische Wahl für Ihre Gesundheit' (The logical choice for your health) suggests that choosing the product is a decision backed by evidence and common sense. It is a word that carries the weight of authority and clarity, making it a favorite for persuasive speech.

Hast du die Hausaufgaben gemacht? - Logisch!

One of the primary pitfalls for English speakers is assuming that logisch is always the best translation for 'makes sense.' While 'Das ist logisch' is perfectly correct, Germans often use the phrase 'Das macht Sinn' (though traditionally criticized by purists as an anglicism) or 'Das ergibt Sinn.' Using 'logisch' when something is merely 'understandable' or 'relatable' might sound a bit too clinical or technical. For example, if a friend is sad because their cat died, saying 'Das ist logisch' would sound incredibly cold and robotic, whereas 'Das ist verständlich' (That is understandable) would be empathetic.

Falsch: Ich bin traurig. - Das ist logisch. (Sounds like a robot speaking.)

Another mistake is the confusion between 'logisch' and 'natürlich.' In English, we might say 'Logically, we should go now,' but in German, if you mean 'naturally' or 'of course,' you might prefer 'Natürlich' or 'Selbstverständlich.' 'Logisch' implies a deduction from facts, while 'Natürlich' implies a natural progression or a social expectation. Mixing these up can make your speech feel slightly 'off' to a native ear.

Overuse of 'Logisch!': While 'Logisch!' is a great colloquialism, using it too much in formal settings to mean 'Yes' can come across as slightly disrespectful or overly casual, as if you are saying 'Duh, obviously.'

Finally, learners sometimes confuse 'logisch' with 'konsequent.' While 'logisch' refers to the reasoning itself, 'konsequent' (consistent/consequent) refers to the action of following through with that logic. If you say someone is 'logisch,' you mean they think clearly. If you say they are 'konsequent,' you mean they act according to their principles or the rules they've set.

To sound more nuanced in German, it is helpful to know when to swap logisch for a more specific synonym. Depending on whether you are talking about an argument, a feeling, or a physical process, different words might be more appropriate. For instance, schlüssig is a fantastic alternative when describing an argument that is coherent and convincing. It suggests that all the pieces of the puzzle fit together perfectly.

Schlüssig vs. Logisch: 'Logisch' is the technical foundation; 'schlüssig' is the persuasive result. An argument can be logisch but not necessarily schlüssig if it doesn't lead to a definitive conclusion.
Nachvollziehbar: This literally means 'traceable.' Use this when you want to say that you can follow someone's reasoning, even if you don't necessarily agree with the logic itself. It is much warmer than 'logisch.'

Deine Erklärung ist absolut nachvollziehbar, auch wenn ich anders entscheiden würde.

Another important word is plausibel. This is used when something sounds 'believable' or 'likely.' While 'logisch' deals with truth and structure, 'plausibel' deals with probability. If a suspect has an alibi that makes sense but isn't necessarily proven by pure logic, you would call it 'plausibel.' For mathematicians and scientists, folgerichtig is a precise term meaning 'following as a consequence.' It is often used in technical writing to show that step B follows step A without exception.

In summary, while 'logisch' is your 'go-to' word for anything that makes sense, expanding your vocabulary to include 'schlüssig,' 'nachvollziehbar,' and 'sinnvoll' will allow you to express the *type* of sense something is making, which is a hallmark of advanced German proficiency.

How Formal Is It?

豆知識

While 'Logik' has been in German since the 14th century, the adjective 'logisch' became much more frequent during the Enlightenment (Aufklärung) in the 18th century as reason became a central cultural value.
