German Grammar Review - Perfekt, Infinitiv mit zu, and Konjunktiv II

Vocabulary and rule flashcards reviewing German conversational past tense (Das Perfekt), infinitival constructions (Infinitiv mit zu / um zu), and polite forms (Konjunktiv II) based on Career-ReadyGerman lecture material.

Das Perfekt

The conversational past tense in German, formed using a conjugated auxiliary verb ('haben' or 'sein') on position 2 and the Partizip II at the very end of the sentence.

Position of Partizip II

Placed at the very end of the sentence in Perfekt tense, remaining at the end even when an object or other information intervenes.

Auxiliary verb 'sein' in Perfekt

Used in Perfekt tense specifically with verbs that denote movement or a change of state/condition (e.g., gehen, kommen, bleiben, werden).

Auxiliary verb 'haben' in Perfekt

Used in Perfekt tense for the vast majority of German verbs covering standard activities and transitive actions.

Regular Partizip II Formation

Formed using the standard formula ge- + verb stem + -t (e.g., machen -> gemacht).

Partizip II for Verbs ending in -ieren

Formed without the 'ge-' prefix, adding only '-t' to the stem (e.g., installieren -> installiert, konfigurieren -> konfiguriert).

Partizip II for Separable Verbs (Trennbar)

Formed by inserting '-ge-' between the separable prefix and the verb stem (e.g., einrichten -> eingerichtet).

Partizip II for Inseparable Verbs (Untrennbar)

Formed without adding 'ge-' when inseparable prefixes such as be-, ver-, or ent- are present (e.g., beheben -> behoben, verwalten -> verwaltet).

beheben (Perfekt)

habe behoben (meaning to remedy or fix).

einrichten (Perfekt)

habe eingerichtet (meaning to set up or configure).

konfigurieren (Perfekt)

habe konfiguriert (meaning to configure).

verwalten (Perfekt)

habe verwaltet (meaning to manage or administer).

Infinitiv mit zu

A sentence structure used to seamlessly link two thoughts, placing 'zu' plus the infinitive verb at the end of the clause.

'zu' with Separable Verbs

In infinitival structures with separable verbs, 'zu' is placed in the middle between the prefix and the stem (e.g., einzurichten, herunterzufahren).

German Infinitiv Triggers

Verbs and expressions that take an infinitive clause with 'zu', such as versuchen, Es ist wichtig, vergessen, anfangen, and Lust / Zeit haben.

um … zu

A structure equivalent to 'in order to' in English, used to express a goal or purpose when both clauses share the exact same subject.

damit (vs. um … zu)

A conjunction used to express a goal or purpose when the intended action concerns a different subject/person (e.g., 'Ich erkläre es, damit der Nutzer es versteht').

Der Konjunktiv II

A German mood providing a polite tone for wishes, requests, and advice, softening demands into requests, commands into advice, and refusals into reservations.

Six Core Konjunktiv II Forms

The primary high-frequency subjunctive forms: würde (werden), könnte (können), sollte (sollen), müsste (müssen), wäre (sein), and hätte (haben).

würde + Infinitiv Rule

Used to construct the Konjunktiv II for general verbs by placing 'würde' in position 2 and the infinitive at the end of the sentence.

Konjunktiv II Error Rule for Core Verbs

'würde' must NOT be combined with the six primary core verbs; direct subjunctive forms are used instead (e.g., 'Ich hätte eine Frage', not 'Ich würde eine Frage haben').

"Ich hätte eine Frage"

An essential interview phrase meaning "I have a question" phrased in polite Konjunktiv II.

"Ich würde zuerst die Ursache prüfen"

An essential interview phrase meaning "I would check the cause first" using Konjunktiv II.

"Das wäre möglich"

An essential interview phrase meaning "That would be possible" using Konjunktiv II.

"Das wäre schwierig"

A polite Konjunktiv II phrasing used to soften a direct refusal into an expression of reservation ("That would be difficult").
