Modal verbs are an essential component of the German language, serving to modify the meaning of the main verb in a sentence. They express various nuances such as ability, necessity, obligation, permission, desire, and preference. The six primary modal verbs in German are “können” (can), “müssen” (must), “sollen” (should), “dürfen” (may), “wollen” (want), and “mögen” (like).
Each of these verbs plays a unique role in communication, allowing speakers to convey their intentions and feelings more precisely. Understanding how modal verbs function is crucial for anyone learning German. They do not stand alone; instead, they are typically used in conjunction with an infinitive verb.
For instance, in the sentence “Ich kann schwimmen” (I can swim), “kann” modifies the action of swimming, indicating the speaker’s ability. This interplay between modal verbs and infinitives is a fundamental aspect of German grammar that learners must grasp to communicate effectively. Learn German at NLS. Sign up for our courses.

Conjugating Modal Verbs in German
Conjugation of modal verbs in German follows specific patterns that differ from regular verbs. Each modal verb has its own set of conjugations based on the subject pronoun. For example, “können” is conjugated as “ich kann,” “du kannst,” “er/sie/es kann,” “wir können,” “ihr könnt,” and “sie/Sie können.” This pattern is consistent across all modal verbs, making it easier for learners to remember their forms once they understand the basic structure.
Moreover, the conjugation of modal verbs does not change in the same way as regular verbs when used in different tenses. Instead, they maintain their unique forms while the main verb remains in its infinitive form. This characteristic can be challenging for learners initially but becomes more intuitive with practice.
Understanding these conjugation rules is vital for constructing grammatically correct sentences and expressing oneself clearly in German.
Using “Können” to Express Ability

The modal verb “können” is primarily used to express ability or capability. It allows speakers to indicate what they can do or what skills they possess. For instance, one might say, “Ich kann gut Deutsch sprechen” (I can speak German well), showcasing their proficiency in the language.
This verb is particularly useful in everyday conversations, as it helps individuals articulate their skills and competencies. In addition to expressing personal abilities, “können” can also be used to discuss the capabilities of others or even objects. For example, “Das Auto kann schnell fahren” (The car can drive fast) illustrates how this modal verb extends beyond personal experience to encompass broader contexts.
Mastering the use of “können” enriches one’s vocabulary and enhances conversational skills, making it a vital aspect of learning German.
Using “Müssen” to Express Necessity
“Müssen” serves as the modal verb that conveys necessity or obligation. It is used when something is required or essential. For example, one might say, “Ich muss zur Arbeit gehen” (I must go to work), indicating a strong obligation to fulfil a responsibility.
This verb is particularly significant in professional and academic contexts, where obligations often dictate actions. Furthermore, “müssen” can also express external pressures or requirements imposed by circumstances or authority figures. For instance, “Wir müssen die Hausaufgaben bis Freitag abgeben” (We must submit the homework by Friday) highlights a deadline that necessitates action.
Understanding how to use “müssen” effectively allows learners to navigate discussions about responsibilities and expectations with greater ease.
Using “Sollen” to Express Obligation
While “müssen” indicates necessity, “sollen” is used to express obligation or recommendation that may not be as forceful. It often implies that there is an expectation or suggestion rather than an absolute requirement. For example, saying “Du sollst mehr Wasser trinken” (You should drink more water) suggests a recommendation for better health rather than an unyielding obligation.
“Sollen” can also reflect societal norms or moral obligations. For instance, one might say, “Man soll die Umwelt schützen” (One should protect the environment), indicating a collective responsibility towards environmental conservation. This subtlety in meaning makes “sollen” an important modal verb for expressing advice and societal expectations, enriching conversations about ethics and personal choices.
Using “Dürfen” to Express Permission

“Dürfen” is the modal verb that conveys permission or the right to do something. It is often used when discussing rules or regulations that govern behaviour. For example, “Darf ich hier parken?” (May I park here?) directly asks for permission regarding an action.
This verb is particularly useful in formal situations where clarity about permissions is necessary. In addition to formal contexts, “dürfen” can also be employed in everyday conversations to express personal boundaries or limitations. For instance, one might say, “Du darfst nicht laut sprechen” (You must not speak loudly), indicating a restriction on behaviour.
Mastering the use of “dürfen” allows learners to navigate social interactions with greater confidence and respect for established norms.
Using “Wollen” to Express Desire
The modal verb “wollen” is used to express desire or intention. It allows speakers to articulate what they want or wish to do. For example, saying “Ich will ins Kino gehen” (I want to go to the cinema) clearly communicates a personal desire for entertainment.
This verb is particularly powerful as it conveys not just intention but also motivation behind actions. Moreover, “wollen” can also reflect collective desires or aspirations. For instance, one might say, “Wir wollen die Welt verbessern” (We want to make the world a better place), indicating a shared goal among a group.
Understanding how to use “wollen” effectively enriches one’s ability to express personal and collective aspirations, making it a vital part of conversational German.
Using “Mögen” to Express Preference
“Mögen,” which translates to “like,” is used to express preferences or fondness for something. It allows speakers to convey their tastes and inclinations in a straightforward manner. For example, saying “Ich mag Schokolade” (I like chocolate) communicates a clear preference for a particular food item.
This verb is particularly useful in social situations where discussing likes and dislikes can foster connections. In addition to expressing personal preferences, “mögen” can also be used in more complex structures to indicate what someone else likes or dislikes. For instance, one might say, “Er mag keine Spinnen” (He does not like spiders), showcasing how this modal verb can be applied beyond personal experience.
Mastering the use of “mögen” enhances conversational skills by allowing learners to engage in discussions about preferences and tastes.
Using Modal Verbs in the Present Tense
Modal verbs are frequently used in the present tense to convey immediate actions or states of being. When using modal verbs in this tense, it is essential to remember that they are conjugated according to the subject pronoun while the main verb remains in its infinitive form. For example, one might say, “Ich kann schwimmen,” where “kann” is conjugated for the first person singular while “schwimmen” stays as the infinitive.
Using modal verbs in the present tense allows speakers to discuss current abilities, obligations, permissions, desires, and preferences effectively. This immediacy makes conversations more dynamic and relevant, as speakers can articulate their current situations and feelings with clarity and precision.
Using Modal Verbs in the Past Tense
When expressing actions or states related to modal verbs in the past tense, learners must employ specific constructions that involve auxiliary verbs such as “haben.” For example, one might say, “Ich habe schwimmen können,” which translates to “I was able to swim.” Here, the past participle of the modal verb is combined with the auxiliary verb to convey past ability. Understanding how to use modal verbs in the past tense is crucial for discussing previous experiences and obligations. It allows speakers to reflect on their past capabilities and responsibilities while providing context for their current situation.
Mastery of this aspect of grammar enhances fluency and enables more nuanced conversations about past events.
Using Modal Verbs in the Future Tense
To express future actions or states using modal verbs, learners must combine them with appropriate future constructions. Typically, this involves using the auxiliary verb “werden” along with the infinitive form of the modal verb. For instance, one might say, “Ich werde gehen können,” meaning “I will be able to go.” This structure allows speakers to articulate future intentions and capabilities effectively.
Using modal verbs in the future tense opens up new avenues for discussion about plans and aspirations. It enables speakers to convey what they hope or expect to do in the future while maintaining clarity about their intentions. Mastering this aspect of modal verbs enriches one’s ability to engage in forward-looking conversations and express future desires confidently.
