If you want to learn German online, understanding the verbs haben (to have) and sein (to be) is absolutely fundamental. They are not only two of the most common verbs used daily but also serve as crucial auxiliary (helping) verbs for forming past tenses, especially the Perfekt tense. Getting haben and sein right is a major step for any German for beginners learner.

In this guide, we'll break down the conjugation of these essential German verbs in the present (Präsens) and simple past (Präteritum) tenses, and most importantly, clarify when to use each, particularly when forming the Perfekt tense. This knowledge is a cornerstone of our structured German curriculum.

Sein (To Be): Conjugation and Usage

Sein is highly irregular, meaning its forms don't follow standard patterns and must be memorized. It's used to describe states of being, identity, location, and characteristics.

'Sein' Conjugation

When to Use 'Sein' as the Main Verb:

• Identity: Ich bin Student. (I am a student.)
• State/Condition: Du bist müde. (You are tired.)
• Location: Er ist zu Hause. (He is at home.)
• Age: Sie ist 30 Jahre alt. (She is 30 years old.)
• Time: Es ist drei Uhr. (It is three o'clock.)

Haben (To Have): Conjugation and Usage

Haben is also irregular, though slightly less so than sein. It's primarily used to indicate possession or experiencing something.

'Haben' Conjugation

When to Use 'Haben' as the Main Verb:

• Possession: Ich habe ein Auto. (I have a car.)
• Experiencing: Wir haben Hunger. (We are hungry / We have hunger.)
• Experiencing: Er hat Kopfschmerzen. (He has a headache.)
• Relationship: Sie hat zwei Brüder. (She has two brothers.)

Mastering German verb conjugation like this is key for fluency, something we emphasize in our speaking-focused German lessons online.

The Big Question: Haben or Sein as Auxiliary Verbs (Perfekt Tense)

The Perfekt tense (present perfect, e.g., "I have eaten," "He has gone") is the most common way to talk about the past in spoken German. It's formed using the present tense of either haben or sein as an auxiliary verb, plus the past participle (Partizip II) of the main verb.

Perfekt = haben/sein (conjugated) + Partizip II (at the end)

The crucial part of German grammar here is knowing *when* to use haben and *when* to use sein. Here's the rule:

Use SEIN as the Auxiliary Verb When:

• The main verb indicates movement from one place to another (A to B):
  • gehen (to go): Ich bin ins Kino gegangen. (I went / have gone to the cinema.)
  • fahren (to drive/travel): Er ist nach Berlin gefahren. (He drove / has driven to Berlin.)
  • fliegen (to fly): Wir sind nach Spanien geflogen. (We flew / have flown to Spain.)
  • kommen (to come): Sie ist spät gekommen. (She came / has come late.)
  • reisen (to travel): Ihr seid viel gereist. (You traveled / have traveled a lot.)
• The main verb indicates a change of state or condition:
  • aufwachen (to wake up): Ich bin früh aufgewacht. (I woke up / have woken up early.)
  • einschlafen (to fall asleep): Das Baby ist schnell eingeschlafen. (The baby fell asleep / has fallen asleep quickly.)
  • sterben (to die): Der alte Mann ist gestorben. (The old man died / has died.)
  • werden (to become): Du bist Arzt geworden. (You became / have become a doctor.)
• With specific verbs: sein (to be), bleiben (to stay), passieren (to happen), geschehen (to happen), gelingen (to succeed).
  • sein: Ich bin in Deutschland gewesen. (I was / have been in Germany.)
  • bleiben: Wir sind zu Hause geblieben. (We stayed / have stayed at home.)
  • passieren: Was ist passiert? (What happened / has happened?)

Use HABEN as the Auxiliary Verb For:

• Most other verbs, including:
  • Transitive verbs (verbs that take a direct object):
    • lesen (to read): Ich habe das Buch gelesen. (I read / have read the book.)
    • sehen (to see): Hast du den Film gesehen? (Did you see / Have you seen the film?)
    • kaufen (to buy): Wir haben ein neues Auto gekauft. (We bought / have bought a new car.)
    • essen (to eat): Er hat Pizza gegessen. (He ate / has eaten pizza.)
    • trinken (to drink): Sie haben Kaffee getrunken. (They drank / have drunk coffee.)
  • Reflexive verbs:
    • sich waschen (to wash oneself): Ich habe mich gewaschen. (I washed / have washed myself.)
  • Modal verbs (when used with another verb in Perfekt, though Präteritum is more common):
    • können (to be able to): Ich habe das nicht gekonnt / machen können. (I couldn't / haven't been able to do that.)
  • Verbs indicating movement without a change of location (e.g., dancing *in one place*):
    • tanzen (to dance): Wir haben die ganze Nacht getanzt. (We danced / have danced all night.)

This distinction between haben and sein as German auxiliary verbs is a common hurdle, but mastering it is essential for accurate past tense formation. Our Online German Course provides ample practice on this topic.
