解説 Computer in your Level:

At the A1 level, the word 'Computer' is introduced as basic vocabulary for everyday objects. It is one of the easiest words for English speakers to learn because it looks and means exactly the same as in English. The primary focus at this stage is learning the correct definite article, which is 'der' (masculine). You will learn to say simple sentences like 'Das ist ein Computer' (That is a computer) or 'Der Computer ist neu' (The computer is new). You will also learn the plural form, which is very simple because it does not change: 'die Computer' (the computers). Teachers will introduce basic verbs associated with the word, such as 'haben' (to have) and 'brauchen' (to need). For example, 'Ich habe einen Computer' (I have a computer) introduces the accusative case ('einen'). You will also learn to express simple locations using the dative case, such as 'Der Computer ist auf dem Tisch' (The computer is on the table). Vocabulary related to the computer, like 'die Maus' (the mouse) and 'die Tastatur' (the keyboard), is also introduced to build a basic technological lexicon. The goal at A1 is simply recognition, correct gender assignment, and very basic sentence construction.

At the A2 level, your ability to use the word 'Computer' expands significantly. You move beyond simple identification and start talking about how you use the computer in your daily routine. You will learn the crucial preposition 'an' combined with the dative case to express working or playing at the computer: 'Ich sitze am Computer' (I am sitting at the computer) or 'Ich arbeite am Computer' (I am working at the computer). This is a very common structure in German. You will also learn separable verbs related to technology, such as 'einschalten' (to turn on) and 'ausschalten' (to turn off). For example, 'Ich schalte den Computer ein' (I turn the computer on). Furthermore, you will begin to describe problems, such as 'Der Computer ist kaputt' (The computer is broken) or 'Der Computer funktioniert nicht' (The computer is not working). You will use the word in the context of writing emails (E-Mails schreiben), surfing the internet (im Internet surfen), and doing homework (Hausaufgaben machen). The focus is on practical, everyday communication regarding technology and routine tasks.

At the B1 level, the word 'Computer' is used in more complex and descriptive contexts. You are expected to handle situations like buying a computer or explaining a technical issue to a repair person. You will learn more advanced verbs like 'hochfahren' (to boot up), 'herunterfahren' (to shut down), and 'abstürzen' (to crash). For example, 'Mein Computer ist gestern abgestürzt' (My computer crashed yesterday). You will also start using compound nouns extensively, such as 'der Computerbildschirm' (the computer screen), 'das Computerprogramm' (the computer program), and 'das Computerspiel' (the computer game). Discussions at this level might involve comparing different types of computers, discussing the advantages of a laptop versus a desktop PC, or talking about the role of computers in the modern workplace. You will use relative clauses to describe the computer: 'Der Computer, den ich gekauft habe, ist sehr schnell' (The computer that I bought is very fast). The focus shifts from basic usage to expressing opinions, describing past events (like a computer breaking down), and navigating customer service scenarios.

The vocabulary expands to include terms like 'die Festplatte' (the hard drive), 'das Betriebssystem' (the operating system), and 'die Softwareentwicklung' (software development). You will be able to write formal emails or reports detailing computer issues or requesting new hardware in a professional setting. For example, 'Aufgrund technischer Mängel beantrage ich einen neuen Computer' (Due to technical defects, I am requesting a new computer). You will also engage in debates about screen time (Bildschirmzeit) and the psychological effects of spending too much time 'am Computer'. The language used is more sophisticated, employing passive voice and complex sentence structures to discuss technological trends and professional IT environments.

Computer 30秒で

A masculine noun (der Computer) meaning an electronic data processing device.
The plural form is identical to the singular: die Computer.
Used with the preposition 'an' (am Computer) when referring to working at it.
Often replaced by synonyms like 'Rechner' or 'PC' in everyday German.

The German word 'Computer' is a masculine noun, which means it uses the definite article 'der' (der Computer) and the indefinite article 'ein' (ein Computer). It is a direct loanword from the English language, and its meaning is identical: an electronic device used for processing data, browsing the internet, working, playing games, and performing countless other digital tasks. In modern German society, the word is ubiquitous. You will hear it in everyday conversations, in professional environments, in schools, and in the media. When Germans talk about their desktop machines, laptops, or even sometimes their tablets, the overarching category is often referred to as 'Computer'.

Mein neuer Computer ist sehr schnell und leise.

Understanding how to use this word is foundational for anyone learning German, as digital literacy and the vocabulary surrounding it are essential in the 21st century. The plural form is remarkably simple for English speakers because it does not change: 'die Computer'. One computer is 'der Computer', and two computers are 'zwei Computer'.

Everyday Usage: Used when referring to a personal computer at home or in the office, often interchangeably with PC.

It is important to note that while the word is borrowed from English, its pronunciation has been slightly Germanized. The emphasis is on the second syllable, and the 'r' at the end is often vocalized as a short 'a' sound, typical for German words ending in '-er'.

Ich arbeite jeden Tag acht Stunden am Computer.

In the workplace, you might hear phrases like 'den Computer hochfahren' (to boot up the computer) or 'den Computer herunterfahren' (to shut down the computer). These separable verbs are crucial to master alongside the noun itself. Furthermore, the word forms the basis of many compound nouns in German, a language famous for its ability to string words together. Examples include 'Computerspiel' (computer game), 'Computerbildschirm' (computer screen), and 'Computerprogramm' (computer program).

Er hat den ganzen Tag am Computer gespielt.

When discussing technical issues, Germans might say 'Der Computer ist abgestürzt' (The computer crashed). This is a very common phrase that every learner should know, as technical difficulties are a universal experience.

Technical Context: In IT and technical fields, the word is used to describe the hardware system, distinct from software or peripherals.

The cultural integration of the word 'Computer' into German is complete. While there is a native German word, 'Rechner' (calculator/computer), 'Computer' is universally understood and arguably more common in casual conversation when referring to a personal computing device.

Wir müssen die Daten auf dem Computer speichern.

Older generations might sometimes use 'Elektronische Datenverarbeitungsanlage' (EDV-Anlage) in highly formal or historical contexts, but this is incredibly rare today. Learning the word 'Computer' opens the door to a vast array of related vocabulary. You will need to know words like 'Tastatur' (keyboard), 'Maus' (mouse), 'Bildschirm' (monitor), and 'Drucker' (printer) to fully describe your digital environment.

Educational Context: Schools in Germany increasingly use computers for teaching, making this a vital word for students and educators alike.

Der Lehrer hat die Hausaufgaben auf den Computer geladen.

In conclusion, 'Computer' is an indispensable noun in the German language. Its masculine gender, unchanged plural form, and extensive use in compound words make it a fascinating and highly practical word for learners of all levels to master early in their language journey.

Using the word 'Computer' correctly in German sentences requires a solid understanding of German cases: Nominative, Accusative, Dative, and Genitive. Because 'Computer' is a masculine noun ('der Computer'), its article changes depending on its grammatical role in the sentence. In the Nominative case, used when the computer is the subject of the sentence, you use 'der'. For example, 'Der Computer ist neu' (The computer is new) or 'Der Computer funktioniert nicht' (The computer is not working).

Der Computer steht auf dem Schreibtisch.

When the computer is the direct object of an action, you must use the Accusative case, which changes 'der' to 'den'. For instance, 'Ich kaufe den Computer' (I am buying the computer) or 'Er repariert den Computer' (He is repairing the computer).

Accusative Case: Use 'den Computer' when it is the direct object, receiving the action of the verb directly.

The Dative case is used for indirect objects or after certain prepositions. The article becomes 'dem'. A very common usage is with the preposition 'an' (at). When you are sitting at the computer, you say 'Ich sitze an dem Computer', which is almost always contracted to 'am Computer'.

Sie verbringt zu viel Zeit am Computer.

Another Dative preposition is 'mit' (with). 'Ich arbeite mit dem Computer' (I work with the computer). The Genitive case indicates possession and changes the article to 'des' and adds an 's' to the noun: 'des Computers'. For example, 'Der Bildschirm des Computers ist kaputt' (The screen of the computer is broken). While the Genitive is sometimes replaced by 'von dem' in spoken German, it remains standard in written German.

Die Tastatur des Computers klemmt.

Genitive Case: Used to show possession. Remember to add the 's' to the end of the noun: des Computers.

Beyond cases, it is vital to know the verbs that frequently collocate with 'Computer'. We use 'einschalten' or 'hochfahren' for turning it on, and 'ausschalten' or 'herunterfahren' for turning it off.

Bitte fahren Sie den Computer nach der Arbeit herunter.

If the computer stops working, the verb 'abstürzen' (to crash) is used with the auxiliary verb 'sein' in the perfect tense: 'Der Computer ist abgestürzt'. When talking about software or files, we use prepositions like 'auf'. 'Das Programm ist auf dem Computer installiert' (The program is installed on the computer).

Preposition 'auf': Use 'auf dem Computer' (Dative) to describe where a file or program is located.

Ich habe viele Fotos auf meinem Computer.

Mastering these sentence structures, cases, and prepositions will make your German sound incredibly natural and fluent when discussing technology. Remember to practice the different cases out loud to get used to the changing articles.

The word 'Computer' is deeply embedded in the daily life of German speakers, and you will encounter it in a wide variety of contexts, ranging from casual conversations at home to highly technical discussions in the workplace. One of the most common places you will hear this word is in the office (das Büro). Colleagues frequently discuss their workstations, IT issues, and software updates.

Mein Computer im Büro ist schon wieder sehr langsam.

In this environment, the word is often used alongside terms like 'Netzwerk' (network), 'Server' (server), and 'Passwort' (password). You will also hear it extensively in educational settings, such as schools (Schulen) and universities (Universitäten). Students talk about writing essays on their computers, researching online, or participating in computer science classes (Informatikunterricht).

Academic Context: In universities, access to a reliable computer is essential, and the word is used daily by students and professors.

Für mein Studium brauche ich einen leistungsstarken Computer.

Another major domain where 'Computer' is a key vocabulary word is the retail sector, specifically in electronics stores like MediaMarkt or Saturn. When you walk into these stores, you will see signs for 'Computer & Zubehör' (Computers & Accessories). Salespeople will ask you what kind of computer you are looking for, what your budget is, and what specifications you need. The gaming community is another area where the word is prevalent. Gamers (Gamer) talk about their 'Gaming-Computer' or 'Spielecomputer'. They discuss hardware upgrades, graphics cards (Grafikkarten), and processors (Prozessoren) needed to run the latest games smoothly.

Er hat sich einen teuren Computer nur für Videospiele gekauft.

Gaming Context: A high-end computer designed for gaming is often a status symbol within the gaming community.

Furthermore, you will hear the word 'Computer' in the context of troubleshooting and tech support. If you call a hotline because your internet is not working, the technician might ask you to restart your computer. 'Haben Sie den Computer schon neu gestartet?' (Have you restarted the computer yet?) is a classic troubleshooting question.

Der Techniker sagte, ich soll den Computer neu starten.

Finally, the word appears frequently in the media, news, and discussions about the future, digitalization, and artificial intelligence. Articles about cyber security, data protection (Datenschutz), and technological advancements will invariably use the word 'Computer' to describe the infrastructure of the modern world.

Media Context: News outlets use the term when discussing cybercrime, hacking, or new technological breakthroughs.

Die Hacker haben Zugriff auf die Computer der Regierung erlangt.

In summary, whether you are buying electronics, working in an office, studying, gaming, or just reading the news, the word 'Computer' is an unavoidable and essential part of the German vocabulary.

When English speakers learn the German word 'Computer', they often make a few predictable mistakes due to the word's English origin and the specific rules of German grammar. The most frequent and glaring mistake is assigning the wrong grammatical gender to the noun. Because 'computer' is an 'it' in English, many learners instinctively want to use the neuter article 'das' in German, saying 'das Computer'. This is incorrect.

Falsch: Das Computer ist teuer. Richtig: Der Computer ist teuer.

'Computer' is a masculine noun in German, so it must always be 'der Computer'. Memorizing the gender of loanwords is crucial, and a good rule of thumb is that many English loanwords ending in '-er' that denote an agent or a device take the masculine gender in German (e.g., der Router, der Laser, der Scanner).

Gender Mistake: Always use 'der', not 'das' or 'die' (unless plural). It is a masculine noun.

Another very common mistake relates to the plural form. In English, we add an 's' to make 'computers'. English speakers naturally want to carry this rule over to German and say 'die Computers'. However, in German, masculine nouns ending in '-er' typically do not change in the plural. Therefore, the plural of 'der Computer' is simply 'die Computer'.

Falsch: Ich habe zwei Computers. Richtig: Ich habe zwei Computer.

Pronunciation is another area where learners stumble. While the word is spelled exactly the same as in English, it is not pronounced with a heavy American or British accent in standard German. The German pronunciation emphasizes the second syllable more cleanly, and the final 'r' is often vocalized into a short 'a' sound (Tiefschwa), sounding somewhat like 'Kom-pju-tah'.

Pronunciation Error: Avoid a strong English 'r' at the end. Soften it to sound more native.

Hör gut zu, wie Deutsche das Wort Computer aussprechen.

Prepositions also cause headaches. English speakers might say 'I am on the computer' and translate it literally to 'Ich bin auf dem Computer'. In German, 'auf dem Computer' means physically standing or sitting on top of the machine, or it refers to data stored on the hard drive. If you mean you are using the computer, you must use 'an'. 'Ich bin am (an dem) Computer'.

Falsch: Ich spiele auf dem Computer. Richtig: Ich spiele am Computer.

Finally, learners sometimes confuse 'Computer' with 'Taschenrechner'. A 'Taschenrechner' is a small pocket calculator used for math. While both compute things, you cannot call a pocket calculator a 'Computer' in German without causing confusion.

Vocabulary Confusion: Do not use 'Computer' for a simple math calculator. Use 'Taschenrechner' instead.

Für die Matheprüfung brauche ich keinen Computer, sondern einen Taschenrechner.

By paying attention to the masculine gender, the unchanged plural, the Germanized pronunciation, and the correct prepositions, you can easily avoid these common pitfalls and sound much more natural when speaking German.

While 'Computer' is the most universally understood term for an electronic data processing device in German, there are several similar words and alternatives that native speakers use depending on the specific context, the type of device, or personal preference. The most prominent native German synonym is 'der Rechner'. Historically, this word meant 'calculator' (someone or something that calculates), but in modern IT and office environments, 'Rechner' is used completely interchangeably with 'Computer'.

Fahr bitte den Rechner herunter, bevor du gehst.

In fact, many IT professionals prefer 'Rechner' because it sounds slightly more integrated into the German language, even though 'Computer' is perfectly fine.

Der Rechner: A very common synonym for Computer, often used in professional or technical contexts. It literally means 'calculator' or 'computing machine'.

Another extremely common alternative is the abbreviation 'der PC' (Personal Computer). Just like in English, 'PC' is used to refer specifically to a desktop computer or a Windows-based machine, as opposed to a Mac. The pronunciation is 'Peh-Tseh'.

Ich habe mir einen neuen PC für mein Homeoffice gekauft.

When referring to portable computers, Germans heavily rely on English loanwords. 'Der Laptop' is universally used and understood. Another very common term for a portable computer is 'das Notebook'. Interestingly, while 'Laptop' is masculine (der Laptop), 'Notebook' is neuter (das Notebook).

Portable Alternatives: Use 'der Laptop' or 'das Notebook' when specifically talking about a portable computer, rather than the generic 'Computer'.

Ich nehme meinen Laptop mit in die Bibliothek.

If you are an Apple user, you will likely just say 'der Mac'. 'Ich arbeite an einem Mac' (I work on a Mac). This brand-specific terminology is just as common in Germany as it is in English-speaking countries. For touch-based devices, the term is 'das Tablet' (pronounced with a German 'a' or sometimes closer to the English pronunciation). While a tablet is technically a computer, calling an iPad a 'Computer' in casual German conversation might sound a bit strange or overly broad.

Das Tablet: Use this for touch-screen devices without a built-in keyboard. It is a neuter noun.

Abends lese ich oft Nachrichten auf meinem Tablet.

Finally, in highly formal, bureaucratic, or historical contexts, you might encounter the term 'die EDV-Anlage' (Elektronische Datenverarbeitungsanlage). This translates to 'electronic data processing system'. You will almost never hear this in daily life, but you might see it in old legal documents or formal company policies regarding IT infrastructure.

Die Wartung der EDV-Anlage findet am Wochenende statt.

Understanding these nuances allows you to choose the most precise word for the situation, whether you are talking about a massive desktop rig (der Rechner/PC) or a small portable device (der Laptop/das Tablet).

豆知識

In the early days of computing in Germany, there was a strong push to use purely German terms like 'Elektronengehirn' (electronic brain) or 'Datenverarbeitungsanlage'. However, the English loanword 'Computer' was shorter, catchier, and ultimately won the vocabulary war.

Computer vs Rechner

It is the native German word for computer.

'Rechner' is often used in professional IT contexts or by native speakers who prefer German terms. 'Computer' is more universal. They mean the exact same thing in modern usage.

Der Rechner ist abgestürzt. / Der Computer ist abgestürzt.

'Computer' often implies a desktop machine (PC), whereas 'Laptop' specifically means a portable one. If you have a laptop, you usually say 'Laptop', not 'Computer'.

Both compute things.

A Taschenrechner is only for math (calculator). A Computer is for general data processing.

よくある間違い

Saying 'das Computer'. → Saying 'der Computer'.
Many English loanwords are masculine in German, especially those ending in -er. It is a common mistake to assume it is neuter because it is an object.
Saying 'die Computers' for plural. → Saying 'die Computer'.
English speakers naturally add an 's' for plural. In German, masculine nouns ending in -er usually do not change in the plural.
Saying 'Ich bin auf dem Computer' to mean 'I am using the computer'. → Saying 'Ich bin am Computer'.
'Auf' means physically on top of. 'An' (am = an dem) means at the boundary of or interacting with the device.
Pronouncing it with a hard English 'R'. → Pronouncing the final 'er' as a soft 'a' (Tiefschwa).
While spelled the same, the phonetics must adapt to German rules to sound natural.
Using 'Computer' for a pocket calculator. → Using 'Taschenrechner' for a pocket calculator.

語源

The word 'Computer' was borrowed directly from English into German in the mid-20th century. The English word itself comes from the Latin 'computare', which means 'to calculate' or 'to reckon'. Initially, a 'computer' was a human being who performed mathematical calculations. With the invention of electronic calculating machines, the term was transferred to the machines. In German, the native word 'Rechner' (calculator) was used heavily at first, but 'Computer' eventually became the dominant term for personal and general-purpose machines.

元の意味： A person who makes calculations.

Latin -> English -> German

文化的な背景

Be aware that older Germans might prefer the term 'Rechner' or might not be as familiar with modern English tech slang. Always be patient when explaining computer issues to older generations.

English speakers must remember to adjust their pronunciation. Do not say it with a heavy American accent; soften the 'r' at the end to sound more German.

Konrad Zuse (inventor of the Z3) Chaos Computer Club (famous German hacker association) 'Neuland' (Angela Merkel's famous quote)

The plural is exactly the same as the singular: 'die Computer'. Do not add an 's' at the end.

You say 'Ich bin am Computer' or 'Ich sitze am Computer'. Do not say 'auf dem Computer', as that means physically on top of it.

It is pronounced similarly to English, but with the stress on the second syllable (Kom-PJU-ter) and a soft, vocalized 'r' at the end, sounding like an 'a'.

It means to boot up or turn on the computer. It is a separable verb, so in a main clause you say 'Ich fahre den Computer hoch'.

No. A smartphone is called 'das Smartphone' or 'das Handy' in German. While technically a computer, calling it one sounds very strange.
