German verbs raise questions that English speakers do not expect: why fahren becomes du fährst, why aufstehen splits into ich stehe... auf, or why helfen takes the dative. This 19-page guide answers them in order, starting with the present tense and moving through the past, modal and separable verbs, the passive, and a set of advanced constructions. Four exercises with a complete answer key close the guide.

Weak, strong and irregular

The present tense section groups verbs by how they behave:

Type	Model verb	What to watch
Weak	machen, arbeiten	regular endings; verbs in -t or -d add an e: du arbeitest
Strong with a→ä	fahren	vowel change in du and er forms: du fährst, er fährt
Strong with e→i	nehmen	du nimmst, er nimmt
Irregular	sein, haben, werden	memorise the full present tense

Grouping strong verbs by their vowel change, as the tips recommend, makes new verbs such as sprechen → du sprichst much easier to predict.

Talking about the past

For conversation, the Perfekt matters most, and the guide says so directly. It is formed with haben or sein and a past participle, usually with ge-: Ich habe ein Buch gelesen, Sie ist nach Hause gegangen. Verbs of movement and change of state take sein. The Präteritum is shown with a weak model (machte) and a strong one (ging), the forms you will meet in written narratives.

Separable and inseparable prefixes

Two sections deal with prefixes, one of the defining features of German verbs:

Separable prefixes such as auf-, an-, mit-, ab-, aus-, and ein- move to the end of a main clause: Ich stehe um 7 Uhr auf, Wann fährt der Zug ab? In a subordinate clause the verb stays together: dass er früh aufsteht.
Inseparable prefixes such as be-, ver-, and ent- never separate and do not take ge- in the participle: Er hat den Film verstanden.

Modals, cases and prepositions

The six modal verbs push the main verb to the end as an infinitive without zu: Ich kann Deutsch sprechen. The guide lists adding zu after a modal among the most common mistakes.

Section 12 is particularly useful because it links verbs to cases. Some verbs take a dative object where English speakers expect a direct object, such as helfen, folgen, gehören, and danken (Ich helfe dem Kind). Others take both a dative person and an accusative thing (Ich gebe dem Kind das Buch), and many combine with a fixed preposition: warten auf, denken an, sich freuen auf, sich interessieren für.

Passive and advanced constructions

The passive is built with werden and a participle: Das Haus wird gebaut. The advanced section then introduces three structures that appear quickly in real texts: the double infinitive with modals (Ich habe arbeiten müssen), infinitives with zu (Es ist wichtig zu lernen), and lassen for having something done (Ich lasse das Auto reparieren).

Checking your forms with the answer key

The exercises cover present conjugation, the Perfekt, separable verbs, and modal verbs, and all answers are included. A good follow-up is to take the four separable verbs from the third exercise and use each one twice: once in a main clause and once after weil, where the prefix rejoins the verb.

Once the first weeks of German are behind you, this overview helps connect the pieces of the verb system.
