German/Grammar/The simple past tense

The simple past tenseEdit

German, much like English, forms the past tense in two ways, one by adding a special ending to the verb, and one by using an auxiliary verb. (Keep in mind though that German does not distinguishes between something happening once and something happening continuously, while English does. If you count these variations then it brings the tally for English up to four.) In this section we'll talk about the one where the ending changes; this is called the preterite or simple past. The other is called the perfect, which will be defined below. Although the German versions are formed similarly to the corresponding tenses in English, they are used rather differently. Both forms require a good amount of explanation, so we'll only cover the simple past in detail here.

The difference between simple past and perfectEdit

In English, the simple past is usually formed by adding "-(e)d" to the end of the verb. For example "I move," becomes "I moved." The perfect tense is formed by combining the auxiliary verb "to have" with a special form of the verb called the past participle. Coincidentally, the past participle is also usually formed by adding "-(e)d" to the verb. So "I move," becomes "I have moved." Note that with irregular verbs the simple past and the participle are often different, and forming the past tense may involve a vowel changes. (Such a vowel change is called and ablaut, as mentioned in the section on stem changing verbs.) For example "I give," becomes "I gave," in the simple past, and "I have given" in the perfect tense. In English the difference in meaning between the two forms can be subtle, but in general the perfect tense implies a sense of completion that the simple past does not. For example "I slept," may mean that you were only sleeping a short time and were woken up before you were ready. But "I have slept," implies you've gotten enough sleep for what you need to do; you are done sleeping for the time being. (In English, the continuous past tenses are the past progressive – "I was sleeping", and the past perfect progressive – "I had been sleeping". Neither of these exist in German.) With verbs which describe a single event, the difference in meaning nearly evaporates, for example "I gave the child a toy," vs. "I have given the child a toy."

Just as German does not distinguish between continuous and non-continuous action, it doesn't really distinguish between complete or incomplete action in the past. This means that the difference in meaning between the simple past and perfect tenses is even more subtle in German than it is in English. In fact, most sentences using either one of the past tenses in English can be translated as either simple past or perfect tense in German and few German speakers would take issue with the meaning. But there is still a preference in German for the simple past over the perfect in certain circumstances. In spoken German, the perfect tense is most common. But the simple past is used when relating an event that took place within a specific time frame, especially when it's part of a sequence of events. You might call the German simple past the "storybook" tense because you would almost always use it when telling a story. Of course this isn't the only time you'd use it, but it might help to keep in the back of your mind that the simple past is a signal that there's a narrative being told, not just a mention of a random occurrence.

But there are other factors besides meaning to consider and it's not really possible to formulate a rule that will work in every situation; often native German speakers themselves don't agree on which past tense to use in some situations. In the spoken language it's partly a matter of regional dialect and in some regions the perfect past is used almost exclusively. Even in areas where the simple past is used more commonly, it's often restricted to more formal situations.

There are certain verbs where the simple past is preferred even in spoken language. In the written language the simple past is sometimes used for incomplete actions as in English. The good news here is that while it may be difficult to predict which is the best form of the past tense to use, it's rare to have a situation where one of the choices is definitely wrong.

Forming the simple pastEdit

Weak verbsEdit

As with English, the German simple past is usually formed by changing the ending. But since German still likes to have different endings for different person and number combinations, the simple past is usually formed by inserting a -t(e)- rather than adding something to the end. Verbs that follow this pattern are called weak verbs to distinguish them from strong verbs which are covered below. The full table is:

Verb endings (Simple Past, Weak Verbs)
Person Singular Plural
First -te -ten
Second (informal) -test -tet
Second (formal) -ten
Third -te -ten

There is an exception in the third person singular in that an -e is added rather than a -t- inserted.

This is how the endings work in practice with the verb hören:

Sentences with hören in the simple past
Person Masculine Feminine Neuter Plural
First Ich hörte.
"I heard."
Wir hörten.
"We heard."
Second (informal) Du hörtest.
"You heard."
Ihr hörtet.
"You heard."
Second (formal) Sie hörten.
"You heard."
Third Er hörte.
"He heard."
Sie hörte.
"She heard."
Es hörte.
"It heard."
Sie hörten.
"They heard."

As with the present tense, stems ending with -d-, -t-, -m- or -n- have an -e- added before the t, assuming there's not one already, to make the word flow more easily. Hence:

  • Ich redete. – "I talked."

Strong VerbsEdit

As in English, some verbs form their simple past tense using a vowel change instead of, or in addition to, a change of ending. This occurs more frequently and more systematically than in English so it's worthwhile to group them into a special class known as strong verbs. (We mentioned strong verbs briefly in the section on stem-changing verbs. All stem-changing verbs are strong but not all strong verbs are stem-changing.) While there are still ending changes for strong verbs, the endings follow a pattern different from weak verbs, and which is more similar to the present tense. The full table for strong verbs is:

Verb endings (Simple Past, Weak Verbs)
Person Singular Plural
First * *-en
Second (informal) *-st *-t
Second (formal) *-en
Third * *-en

Here, the * means that a vowel change occurs. Each verb has its own vowel change, and it's probably easiest just to memorize what the change is separately for each verb. Fortunately, the change is the same for each number and person combination. Note that the endings are the same as the present tense except for the first and third person singular, and there the ending is dropped altogether.

For the stem-changing, hence strong, verb schlafen this works as follows:

Sentences with schlafen, simple past tense
Person Masculine Feminine Neuter Plural
First Ich schlief.
"I slept."
Wir schliefen.
"We slept."
Second (informal) Du schliefst.
"You slept."
Ihr schlieft.
"You slept."
Second (formal) Sie schliefen.
"You slept."
Third Er schlief.
"He schlief."
Sie schlief.
"She slept."
Es schlief.
"It slept."
Sie schliefen.
"They slept."

Some possible vowel changes are:

  • a to ie, as seen above with schlafen.
  • ä to i, as in hängen:
    • Ich hänge – "I hang"
    • Ich hing – "I hung"
  • au to ie, as in laufen:
    • Ich laufe – "I run"
    • Ich lief – "I ran"
  • e to a, an in sehen, rennen, sprechen:
    • Ich sehe – "I see"
    • Ich sah – "I saw"
  • ei to ie, as in bleiben:
    • Ich bleibe – "I remain"
    • Ich blieb – "I remained"
  • i to a, as in singen:
    • Ich singen – "I sing"
    • Ich sang – "I sang"
  • ie to a, as in liegen:
    • Ich liege. – "I lie (position)"
    • Ich lag. – "I lay"
  • o to a, as in kommen:
    • Ich komme – "I come"
    • Ich kam – "I came"

Due to German spelling rules, a vowel change may entail minor changes in stem in the written form. For example there may be change between t and tt, ck and k, ss and , or an h my be lost or gained. These changes don't affect pronunciation, at least not by much, so the verbs are still considered regular strong verbs.

Similarity with past-like presentEdit

We said that past-like present verbs were so named because their present tense is similar to the past tense, meaning the past tense of a strong verb. Let's compare them. Their endings are the same but they are different from the corresponding endings of the present tense for regular verbs. There is a difference however in that the vowel always changes in the past tense, but only in the singular for past-like present, and then not for Sie. (Much like "you", which was originally a polite form in English, "Sie" was adapted from a plural form to a polite form.)

Irregular verbsEdit

Within both the weak and strong categories, there are both regular and irregular verbs. This produces four classes of verbs: weak, irregular weak, strong and irregular strong. Irregular weak verbs follow the weak past tense pattern for the most part, for example the first person singular ending is -te, but differ from the pattern in detail. Irregular strong verbs follow the strong past tense pattern, so they have no first person singular ending, but differ from that pattern in other ways. The class of regular strong verbs can also be divided into stem-changing and non-stem-changing verbs, bringing the tally of classes up to five, and the past-like present verbs bring it up to six. Finally, there is a handful of verbs which follow both strong and weak patterns in some way, and so don't really fit into either group. We'll just call them variable, but they bring the tally to seven.

This may seem complex, but understanding these patterns will greatly decrease what you have to memorize in order to properly conjugate verbs. Even with the most irregular verbs, are similarities with the common patterns which can make memorization easier.

Irregular weak verbsEdit

These follow the weak past ending pattern, but change the stem as well, often with just a vowel change. For example:

  • bringen – "to bring"
    • Ich bringe – "I bring"
    • Ich brachte – "I brought"
  • denken – "to think"
    • Ich denke – "I think"
    • Ich ich dachte – "I thought"
  • brennen – "to burn"
    • Ich brenne – "I burn"
    • Ich brannte – "I burned"
  • kennen – "to know"
    • Ich kenne – "I know"
    • Ich kannte – "I knew"
  • nennen – "to name"
    • Ich nenne – "I name"
    • Ich nannte – "I named"
  • rennen – "to run"
    • Ich renne – "I run"
    • Ich rannte – "I ran"
  • haben – "to have"
    • Ich habe – "I have"
    • Ich hatte – "I had"
  • senden – "to broadcast" or "to send"
    • This is regular in it's meaning "to broadcast", but is usually irregular with past tense stem sand- in the meaning "to send".
    • Ich sende – "I send"
    • Ich sandte – "I sent"

You may recall that haben is irregular in the present tense, but all the others here are regular in the present tense.

Irregular strong verbsEdit

These verbs follow the strong past ending pattern in the simple past tense, but have stem changes other than a simple vowel change. Although the stem is different than expected, simple past tense conjugation can be found by adding the appropriate strong endings to a common stem. Many of these are regular in the present tense:

  • stehen – "to stand"
    • Ich stand – "I stood"
  • sitzen – "to sit"
    • Ich saẞ – "I sat"
  • leiden – "to suffer"
    • Ich litt – "I suffered"
  • gehen – "to go"
    • Ich ging – "I went"
  • ziehen – "to pull"
    • Ich zog – "I pulled"

Two special cases with this group are:

  • tun – "to do"
    • This verb is fairly regular except for the infinitive. In the simple past it's conjugated like a strong verb with the stem tat-
    • Ich tat – "I did"
  • sein – "to be"
    • This is very irregular in the present tense, but in the simple past tense it follows the strong pattern but with the stem war-. These past tense forms are cognates to the English "was" and "were".
    • Ich war – "I was"

Past-like present verbsEdit

These verbs follow the weak pattern in the past tense; this is somewhat ironic since they are so similar to the strong past pattern in the present tense. They sometimes undergo a vowel change, but not the same as the change in present tense. A special case is mögen since the g becomes ch.

  • dürfen – "may"
    • Ich durfte – "I was allowed to"
      • The vowel changes from ü to u.
  • können – "can"
    • Ich konnte – "I could"
      • The vowel changes from ö to o.
  • mögen – "may, to like"
    • Ich mochte – "I might have"
      • This undergoes a stem change in addition to a vowel change, so it might be considered an irregular past-like present verb.
  • müssen – "must"
    • Ich musste – "I had to"
      • The vowel changes from ü to u.
  • sollen – "should"
    • Ich sollte – "I was supposed to"
      • No vowel change.
  • wissen – "to know"
    • Ich wusste – "I knew"
      • The vowel changes from i to u.
  • wollen – "to want"
    • Ich wollte – "I wanted"
      • No vowel change.

Note that some gymnastics are required for the translations into English since the English versions often have no past tense.

Variable verbsEdit

These verbs follow neither the strong or weak pattern completely. Many are strong for some meanings and weak for others.

  • werden – "to become"
    • We said in the section on uninflected adjectives that werden acts like a stem changing verb in the present tense. But in the simple past it acts more like a weak verb, and since stem changing verbs are strong it's best to say it "acts like" a stem changing verb rather than actually being one. In fact it's conjugated almost exactly like a weak verb in the simple past except that the -det- syllable you'd expect is reduced to -d-:
    • Ich werde – "I became"
  • schaffen – "to create or make" or "to manage or succeed"
    • In the sense "to create or make" it's strong and has a vowel change from a to u. But in the sense of "to manage or succeed" it's weak.
  • backen - "to bake" or "to stick (together)"
    • This is weak for some meanings, and either strong or weak for others according to the speaker's taste. In many cases both strong and weak forms exist, but they are not used much and there is no difference in meaning between the two. We refer you to the Usage Notes section in Wiktionary for more details.
  • mahlen - "to grind", salzen - "to salt", spalten - "to split"
    • For the most part these are regular weak verbs. But we'll see that they sometimes follow a strong pattern when we get to the section on participles.

Right Hand RulesEdit

The "Right Hand Rules" law holds for verb conjugation as we mentioned in the section on prefixed verbs, and it still holds for the simple past tense.

Verbs which usually use the simple pastEdit

As we mentioned above, the simple past is preferred for certain verbs even in spoken language. Here is a partial list. We've included the meaning as well when the simple past is preferred for some, but not all meanings of the verb. Again, other verbs might be added and some of the ones we've listed might be removed depending on region.

  • sein
    • Ich war in der Küche. – "I was in the kitchen."
  • haben
    • Ich hatte einen Hund. – "I had a dog."
  • Modal verbs, including wollen and mögen in their non-modal meanings.
    • Ich wollte einen Hund. – "I wanted a dog."
    • Sie mochte Katzen. – "She liked cats."
  • finden when used to express an opinion.
    • Ich fand den Film langweilig. – "I found the movie boring."
  • geben in the impersonal sense.
    • Hier gab es ein Haus. – "There was a house here."
  • The modal-adjacent verb lassen
    • Er ließ mich sein Haus bauen. – "He had me build his house."
  • For verbs related to what you know, denken, wissen and kennen, the simple past and the perfect can both be used in the spoken language.
    • Ich kannte den Weg. – "I knew the way."
