Comprehensive Study Notes on German Verb Valency and Prepositions

Prepositional Variations of the Verb Kämpfen

The German verb "kämpfen" (to fight or struggle) can be used with various prepositions to change its meaning and context. In the example "Der Schwimmer kämpfte mit den Wellen," the preposition "mit" followed by the dative is used to describe a struggle against physical elements, specifically a swimmer battling waves. When expressing an effort to achieve a positive goal, the preposition "für" followed by the accusative is employed, as seen in the phrase "Wir kämpfen für eine bessere Zukunft," which translates to fighting for a better future.

Conversely, when fighting for a cause, a right, or an object of value, the preposition "um" (accusative) is used, illustrated by "Wir kämpfen um unsere Rechte" (we fight for our rights). Finally, to denote a direct conflict or competition against an opponent, "gegen" (accusative) is used: "Die Mannschaft kämpft gegen einen starken Gegner," meaning the team is fighting against a strong opponent.

Adherence, Academic Integrity, and Disturbance

Rule $57$ involves the reflexive construction "sich halten an" followed by the accusative case. This expression means to adhere to or comply with something. The transcript provides the example "Alle müssen sich an die Regeln halten," emphasizing that everyone must follow the rules.

Rule $58$ covers "abschreiben" (to copy), which uses the accusative for the object being copied and the preposition "von" with the dative for the source. An academic context is provided: "Er hat die Hausaufgabe von den anderen abgeschrieben," indicating $\text{he}$ copied the homework from the others. Numerical reference $80800$ appears in conjunction with this entry in the source material.

Rule $59$ describes the verb "stören" (to disturb), which takes a direct accusative object and the preposition "bei" with the dative to signify the activity being interrupted. The example given is "Das Kind stört den Vater bei der Arbeit," or the child disturbs the father while/at work.

Engagement, Recognition, and Connectivity

Rule $60$ introduces the synonymous reflexive verbs "sich beschäftigen" and "sich befassen," both used with the preposition "mit" and the dative case. This means to occupy oneself with or deal with a topic. The example "Mein Opa hat sich oft mit der Gartenarbeit beschäftigt" shows the subject's grandfather often occupying himself with gardening work.

Rule $61$ details "erkennen" (to recognize), which uses the accusative for the entity recognized and "an" plus the dative for the identifying feature. This is exemplified by "Man kann sie an ihrer Stimme erkennen," meaning one can recognize her by her voice.

Rule $62$ outlines "verbinden" (to connect), which takes an accusative object and "mit" plus the dative. The practical example provided is "Ein Kabel verbindet das Gerät mit dem Netz," where a cable connects the device to the network.

Expressions of Laughter, Mockery, and Conflict

Rules $63$ and $64$ relate to reactions toward others. "Lachen über" (Rule $63$) requires the accusative and means to laugh about someone or something, as in "Man lacht über ihn." "Spotten über" (Rule $64$) also uses the accusative and means to mock or scoff. The transcript combines these in the phrase "Sie lachten und spotteten über ihn," describing a scenario where people were laughing and mocking him.

Rule $65$ details the complex valency of "sich streiten" (to argue). One argues "mit" (dative) someone, "über" (accusative) a specific topic, or "um" (accusative) an object or goal. Two examples are provided. First, "Die Abgeordneten streiten sich mit den Journalisten über politische Fragen," involving members of parliament arguing with journalists about political questions. Second, "Sie streitet sich mit ihrem Bruder um nichts," demonstrating a sister arguing with her brother over nothing.

Demands, Protection, and Physical Injury

Rule $66$ involves “verlangen” (to demand). This verb takes an accusative object for the thing demanded and "von" plus the dative for the person from whom it is demanded. Example: "Er verlangt von seinen Studenten Pünktlichkeit," meaning he demands punctuality from his students.

Rule $67$ discusses protection. The verbs "sich schützen" (reflexive) and "schützen" (transitive) use the prepositions "vor" (dative) or "gegen" (accusative). Practical health and environmental examples include: "Mit einer Impfung kann man sich einfach vor einer Grippeerkrankung schützen" (using a vaccination to protect oneself from the flu) and "Warme Kleidung schützt dich vor Kälte" (warm clothing protects you from the cold).

Rule $68$ describes "(sich) verletzen an" (to injure oneself on/at) followed by the dative. The transcript specifies a head injury: "Er verletzte sich am Kopf."

Spatial Movement and Social Complaints

Rule $69$ covers verbs of passing by: "vorbeigehen," "vorbeikommen," and "vorbeifahren." These can take "an" plus the dative to mean passing by a location (e.g., "Ich bin an der Post vorbeigegangen" - I walked past the post office) or "bei" plus the dative to mean stopping by a place or person (e.g., "Wir müssen noch bei der Apotheke vorbeifahren" - we still have to drive by/stop by the pharmacy).

Rule $70$ explains that "sich beschweren" and "sich beklagen" are synonymous verbs for complaining. They use "bei" (dative) for the person receiving the complaint and "über" (accusative) for the subject of the complaint. The example is: "Weder die Bibliothekarin noch der Busfahrer beschweren sich bei den Besuchern über ihre anstrengende Arbeit," noting that neither the librarian nor the bus driver complain to the visitors about their strenuous work.

Lending, Borrowing, and Obstruction

Rule $71$ clarifies the dual nature of "ausleihen." To lend something TO someone (71a), one uses the dative of the person or "an" plus the accusative (e.g., "Ich habe ihm / an ihn ein Buch ausgeliehen"). To borrow something FROM someone (71b), one uses "sich ausleihen" with "bei" or "von" plus the dative (e.g., "Ich habe mir ein Buch bei/von meinem Freund ausgeliehen").

Rule $72$ discusses "hindern" (to hinder or prevent), which takes an accusative object representing the person hindered and either "an" or "bei" followed by the dative for the activity. The example given is "Der Lärm hinderte ihn am Sprechen," meaning the noise hindered/prevented him from speaking.
