The Grammar Interrogation
The Five Grammatical Interrogations
When a gap is grammatical (article + ___ + noun, or wurde + ___, or hätte + ___), you run five questions in order. Each question eliminates suspects faster than the last.
Interrogation 1 — The Case Detector
Roughly six gaps per paper hinge on case. The signal is almost always a preposition or a case-governing verb to the left of the gap.
The Preposition Cheat-Sheet
| Always Akkusativ | Always Dativ | Always Genitiv |
|---|---|---|
| durch, für, gegen, ohne, um, bis, entlang | aus, bei, mit, nach, seit, von, zu, gegenüber | trotz, wegen, während, (an)statt, aufgrund, mittels, hinsichtlich, angesichts |
| Wechselpräpositionen (Akk. for movement / Dat. for location) |
|---|
| an, auf, hinter, in, neben, über, unter, vor, zwischen |
Worked Example — Case + Adjective Combined
Step 1: aufgrund → Genitiv. Step 2: Lage = feminine. Step 3: der = definite article → weak declension. Step 4: Genitiv feminine + weak declension → adjective ending must be -en. Step 5: a second adjective wirtschaftlichen follows; parallel adjectives take the same ending.
Notice: I never had to know what angespannt means. The grammar alone closed the case.
Interrogation 2 — The Adjective Declension Map
Three to four gaps per paper test declension. Recall the rule from your Detective Guide to Adjective Declension: identify article type first, then case + gender. Here is the compressed table you must have automatic.
| After der-words (weak) | Mask | Fem | Neut | Plural |
|---|---|---|---|---|
| Nom | -e | -e | -e | -en |
| Akk | -en | -e | -e | -en |
| Dat | -en | -en | -en | -en |
| Gen | -en | -en | -en | -en |
| After ein-words (mixed) | Mask | Fem | Neut | Plural |
|---|---|---|---|---|
| Nom | -er | -e | -es | -en |
| Akk | -en | -e | -es | -en |
| Dat | -en | -en | -en | -en |
| Gen | -en | -en | -en | -en |
| No article (strong) | Mask | Fem | Neut | Plural |
|---|---|---|---|---|
| Nom | -er | -e | -es | -e |
| Akk | -en | -e | -es | -e |
| Dat | -em | -er | -em | -en |
| Gen | -en | -er | -en | -er |
Interrogation 3 — The Verb Chain
Two to three gaps per paper sit inside a verb chain (Modalverb + Infinitiv, Perfekt with haben/sein + Partizip II, Vorgangspassiv, Konjunktiv II). The grammar of the surrounding chain dictates the gap form.
The Five Verb-Chain Patterns
| Pattern | Structure | Gap is… |
|---|---|---|
| Modalverb | kann / muss / soll / ___ + Infinitiv at end | infinitive (no zu) |
| Perfekt | habe/bin + ___ Partizip II | Partizip II form, often with prefix ge- |
| Vorgangspassiv | wird/wurde + ___ Partizip II | Partizip II of the action verb |
| Zustandspassiv | ist/war + ___ Partizip II | Partizip II describing a state |
| Konjunktiv II Vergangenheit | hätte/wäre + ___ Partizip II | Partizip II + sometimes Modalverb infinitive |
Worked Example — The Konjunktiv II Chain
Verb chain analysis: first clause = Konjunktiv II Vergangenheit Aktiv (hätte reagiert). Second clause = Konjunktiv II Vergangenheit + Passiv + Modalverb (könnte vermieden worden sein → in this construction the auxiliary becomes hätte + vermieden werden können, the famous double-infinitive at the end).
Why hätte? Because the structure vermieden werden können (Modalverb + Infinitiv Passiv) demands haben as auxiliary, not sein. Würde would force a present-tense reading. Könnte is already lexicalised in können at the end of the chain.
Interrogation 4 — The Pronoun Lineup
One to two gaps per paper test reference: relative pronouns, demonstratives, or da/wo-compounds. The signal is a comma, a Bezugswort (referent), and an empty slot.
Relative Pronoun Decision Tree
| Mask | Fem | Neut | Plural | |
|---|---|---|---|---|
| Nom | der | die | das | die |
| Akk | den | die | das | die |
| Dat | dem | der | dem | denen |
| Gen | dessen | deren | dessen | deren |
Worked Example — Relative Pronoun
Bezugswort: das Buch → neuter, singular. Function inside relative clause: Autor belongs to the book → possessive → Genitiv. Neuter singular Genitiv → dessen.
Interrogation 5 — The Pronominaladverb (da- / wo-)
Roughly one gap per paper tests da-compounds (damit, dafür, darauf, daran, davon) or wo-compounds (womit, wofür, worauf, woran, wovon). The trigger is always a verb-preposition collocation pointing back at a fact, idea, or full clause.
| Use | Form | Trigger |
|---|---|---|
| Refers back to a fact / clause | da- + preposition (damit, davon, daran) | verb requires preposition; antecedent is a thing or idea, not a person |
| Anticipates a dass-clause or infinitive | da- + preposition | verb + preposition pointing forward to a clause |
| Question word for things / ideas | wo- + preposition (worüber, woran, wofür) | indirect or direct question about a non-person |
Worked Example — da-Compound
Verb: sich freuen über + Akk. Antecedent: a dass-clause. Therefore: we need da-compound that anticipates the dass-clause: darüber.
Solved Exercise — Refresher
Run the five interrogations on each gap before reading the answer.
Gap 1
Interrogation: trotz → Genitiv. Bemühungen = plural. No article (zero-article construction with abstract plural). Strong declension, Genitiv plural → -er. Answer: intensiver.
Gap 2
Interrogation: muss … werden = Modalverb + Vorgangspassiv. The slot demands a Partizip II. fertigstellen is separable but in Partizip II it remains fertiggestellt (the prefix fertig behaves like a separable particle, so ge- sits between). Answer: fertiggestellt.
Gap 3
Interrogation: Bezugswort = die Kollegin → fem. sg. Inside the clause: jemandem etwas weiterleiten → indirect object → Dativ. Fem. sg. Dativ relative pronoun → der. Answer: der.
Gap 4
Interrogation: Konjunktiv II Vergangenheit. handeln uses haben as auxiliary. Mirror tense from gewusst hätte. Answer: hätte.
Gap 5
Interrogation: sich konzentrieren auf + Akk. Antecedent is a was-clause → da-compound anticipating a clause: darauf. Answer: darauf.
