Simple Past Irregular Verbs in German

In Brief

Strong German verbs form the Präteritum (simple past) with a changed stem vowel and without the regular past marker -te: gehen → ging, schreiben → schrieb, finden → fand. Add -st for du, -en for wir and sie/Sie, and -t for ihr; ich and er/sie/es use the bare past stem.

Overview

The Präteritum is a one-word past tense: ich ging means “I went,” while sie schrieb means “she wrote.” It is essential for reading German because narratives, biographies, reports, and news writing use it extensively. At B1, you should also begin using it when telling a connected story in writing.

This article focuses on strong verbs: irregular verbs whose stem vowel changes, as in kommen → kam and sehen → sah. A stem is the central part of a verb to which personal endings are added. English has comparable changes in “sing → sang” and “write → wrote,” but the German and English patterns do not always match: English “found” corresponds to German fand, but English “went” corresponds to ging, not a form resembling gehen.

German also has the Perfekt, a past tense made with an auxiliary verb (a helping verb, haben or sein) and a past participle: ich bin gegangen, sie hat geschrieben. In most everyday conversation, speakers prefer the Perfekt for many full verbs. The Präteritum remains especially frequent in writing, and several common verbs also occur naturally in the Präteritum in speech.

How It Works

The core formation rule

Begin with the irregular Präteritum stem and add a small set of endings. For finden, the past stem is fand-.

Person	Ending	finden	English
ich	—	ich fand	I found
du	-st	du fandst	you found
er/sie/es	—	er fand	he found
wir	-en	wir fanden	we found
ihr	-t	ihr fandet	you all found
sie/Sie	-en	sie/Sie fanden	they/you (formal) found

The first- and third-person singular forms have no personal ending. This makes ich ging and sie ging identical apart from the subject. The plural endings resemble present-tense endings, but they attach to the changed past stem.

An extra e for pronounceability

If a past stem ends in -d or -t, an extra e normally appears before the ihr ending: ihr fandet, ihr hieltet. With du, the written form can contain a cluster of consonants: du fandst, du hieltst. These forms are correct even if they initially look awkward.

Infinitive	Past stem	ich / er / sie / es	du	wir / sie / Sie	ihr
gehen	ging-	ging	gingst	gingen	gingt
kommen	kam-	kam	kamst	kamen	kamt
schreiben	schrieb-	schrieb	schriebst	schrieben	schriebt
finden	fand-	fand	fandst	fanden	fandet
halten	hielt-	hielt	hieltst	hielten	hieltet

Learn three principal forms

There is no single reliable rule that lets you predict every strong verb’s past vowel. Learn each verb with its principal forms (the key forms from which other forms can be recognized):

Infinitive	3rd-person Präteritum	Past participle	English
gehen	ging	gegangen	go
kommen	kam	gekommen	come
schreiben	schrieb	geschrieben	write
finden	fand	gefunden	find
sehen	sah	gesehen	see
nehmen	nahm	genommen	take
sprechen	sprach	gesprochen	speak
bleiben	blieb	geblieben	stay
lesen	las	gelesen	read
geben	gab	gegeben	give

Families such as schreiben → schrieb and bleiben → blieb can make memorization easier, but treat them as learning patterns, not rules that apply to every similar-looking verb.

Strong verbs versus mixed verbs

Not every irregular verb is strong. Mixed verbs combine a changed stem with the regular -te ending: denken → dachte, bringen → brachte, kennen → kannte, wissen → wusste. They are irregular, but they do not follow the ending pattern taught here. In particular, do not remove -te from dachte or add it to ging.

Separable and inseparable prefixes

A separable prefix moves to the end of a main clause in the Präteritum, just as it does in the present:

• Er stand um sechs Uhr auf. — He got up at six.
• Ich nahm meinen Ausweis mit. — I took my ID with me.
• Der Zug kam spät an. — The train arrived late.

In a subordinate clause (a clause introduced by words such as weil or als), the conjugated verb goes to the end and the prefix remains attached: …, weil der Zug spät ankam. Inseparable prefixes such as be-, ver-, and ent- never split: Sie verstand die Frage.

Examples in Context

German	English	Note
Ich ging nach Hause.	I went home.	gehen → ging
Er schrieb einen Brief.	He wrote a letter.	schreiben → schrieb
Sie kam zu spät.	She arrived too late.	kommen → kam
Wir fanden ein ruhiges Café.	We found a quiet café.	First-person plural
Sahst du den Unfall?	Did you see the accident?	Question with du
Die Kinder lasen die ganze Nacht.	The children read all night.	lesen → las
Ihr nahmt den falschen Bus.	You all took the wrong bus.	ihr ending -t
Der Film begann um acht Uhr.	The film began at eight.	Inseparable be- prefix
Mara stand früh auf.	Mara got up early.	Separable verb aufstehen
Der Zug kam erst nach Mitternacht an.	The train did not arrive until after midnight.	Separable verb ankommen
Als ich ihn traf, trug er einen roten Mantel.	When I met him, he was wearing a red coat.	Two strong past forms
Sie blieb zu Hause, weil sie sich nicht gut fühlte.	She stayed home because she did not feel well.	Strong blieb with regular fühlte
Niemand wusste, warum er plötzlich verschwand.	Nobody knew why he suddenly disappeared.	Mixed wusste; strong verschwand
Nachdem sie die Nachricht las, rief sie ihre Schwester an.	After she read the message, she called her sister.	Written narrative sequence

German does not use a form equivalent to English “did” to make Präteritum questions or negatives. Sahst du ihn? is literally structured as “Saw you him?”, and Ich sah ihn nicht uses the past form itself.

Common Mistakes

Adding the regular -te ending

• Wrong: Ich gingte nach Hause.
• Right: Ich ging nach Hause.
• Why: Strong verbs change the stem vowel and do not add the regular Präteritum marker -te.

Keeping the infinitive’s vowel

• Wrong: Sie komm gestern spät.
• Right: Sie kam gestern spät.
• Why: The form needs both the irregular past stem and the appropriate personal ending. For third-person singular, the ending is zero, but the vowel still changes.

Using the wrong personal ending

• Wrong: Wir gingen nach Hause, aber ihr gingen ins Restaurant.
• Right: Wir gingen nach Hause, aber ihr gingt ins Restaurant.
• Why: Use -en with wir and sie/Sie, but -t with ihr.

Treating every irregular verb as a strong verb

• Wrong: Er dach lange nach.
• Right: Er dachte lange nach.
• Why: denken is a mixed verb: it changes its stem and also takes -te. Learn denken – dachte – gedacht as a set.

Forgetting to separate a prefix

• Wrong: Der Zug ankam um neun Uhr.
• Right: Der Zug kam um neun Uhr an.
• Why: In an independent main clause, a separable prefix goes to the end. However, it stays attached at the end of a subordinate clause: …, weil der Zug um neun Uhr ankam.

Mixing Präteritum and Perfekt inside one verb phrase

• Wrong: Ich bin nach Hause ging.
• Right: Ich ging nach Hause. / Ich bin nach Hause gegangen.
• Why: Choose either the one-word Präteritum or the auxiliary-plus-participle Perfekt. Do not combine their pieces.

Usage Notes

Written and spoken German

English uses its simple past freely in both speech and writing. German divides the work differently. In informal conversation, speakers commonly say Ich bin nach Hause gegangen rather than Ich ging nach Hause. In a written story, Ich ging nach Hause is entirely normal and often preferable.

This is a tendency, not a ban. Northern German speech generally allows more Präteritum than southern German, Austrian, or Swiss usage. Individual verbs also behave differently. sein, haben, and the modal verbs are very common in spoken Präteritum: Ich war müde, Wir hatten keine Zeit, Sie konnte nicht kommen. Some speakers also naturally use frequent forms such as ging, kam, fand, and wusste in conversation.

Keeping a narrative consistent

A written narrative usually uses Präteritum as its main timeline: Er öffnete die Tür, trat ein und sah sich um. A shift to Perfekt can sound conversational or mark a change in viewpoint. Learners do not need to avoid every tense change, but should not alternate randomly sentence by sentence.

Translation is about context, not labels

The German Präteritum can correspond to several natural English past constructions. Als ich nach Hause ging, regnete es can be translated as “When I was walking home, it was raining,” even though both German verbs are in the same tense. German does not require a separate progressive form equivalent to English “was walking.” Context and adverbs show whether an event was ongoing, repeated, or completed.

Beyond the Basics / Advanced Use

Similar forms in the subjunctive

The subjunctive (a verb form used for hypothetical, wished-for, or indirectly reported situations) can resemble the Präteritum. Strong verbs often add an umlaut and -e in Konjunktiv II: fand → fände, kam → käme, gab → gäbe. Compare:

• Er kam gestern. — He came yesterday. (past fact)
• Er käme gern mit. — He would like to come along. (hypothetical)

Some forms are identical, especially where no umlaut is possible. Context then decides the meaning, and everyday German often uses würde + infinitive to make the hypothetical meaning clearer.

Past-before-past in narratives

When one event happened before the main Präteritum timeline, German can use the Plusquamperfekt (past perfect, formed with hatte or war plus a past participle):

• Nachdem sie den Brief gelesen hatte, rief sie an. — After she had read the letter, she called.
• Er war schon gegangen, als ich ankam. — He had already left when I arrived.

This contrast helps readers track the order of events. The foreground actions are rief and ankam; the earlier actions are gelesen hatte and war gegangen.

Narrative style and literary use

Long-form fiction may maintain Präteritum across dialogue tags, description, action, and thought: Sie öffnete das Fenster. Draußen fiel Schnee. „Was geschah hier?“, fragte sie. Advanced literary writing also chooses between short Präteritum forms and longer constructions for rhythm and emphasis. Recognizing strong forms quickly is therefore a reading skill as much as a conjugation skill.

Practice Tips

1. Learn verbs in threes. Record gehen – ging – gegangen rather than memorizing ging alone. This connects the Präteritum with the Perfekt and prevents invented forms.
2. Build families, then test exceptions. Group forms such as schreiben – schrieb and bleiben – blieb, but check each new verb rather than guessing from spelling.
3. Retell a short event twice. Tell it aloud in conversational Perfekt, then rewrite it in Präteritum. For example, change Ich bin angekommen und habe meine Freundin gesehen to Ich kam an und sah meine Freundin.
