weil

Because (Weil)

Level 2

weil = because. It explains the reason for something and requires the verb to move to the end of its clause.

How It Works

The conjunction weil is the most common way to express causality in German. It follows specific rules of subordinate clause word order:

  • Verb Placement: The conjugated (finite) verb moves to the end of the clause. If there are two verbs (like a modal verb and an infinitive), the conjugated one is still last. (Note: In advanced double infinitive constructions, the conjugated verb must appear before the infinitives).
  • weil vs. denn: Both mean 'because', but denn does not change the word order (it occupies Position 0), whereas weil sends the verb to the end.
  • Separable Verbs: In a weil-clause, separable verbs rejoin; the prefix is attached to the front of the conjugated verb at the end of the sentence.
  • Punctuation: A comma is mandatory to separate the main clause and the weil-clause, regardless of which one comes first.
  • Sentence Position: A weil-clause can come first or stand alone as an answer to a Warum? question. If it comes first, the main clause must start with a verb (this is called inversion).
  • Nuance: weil is used to introduce new information or the specific reason for an action, whereas da (since/as) is often used when the reason is already known or serves as background information.
  • weil vs. wegen: Use weil to connect two clauses ('because it is raining'). Use wegen (because of) before a noun phrase in the genitive case (or dative in colloquial speech) ('because of the rain').

In casual spoken German, you might hear people keep the verb in the second position (like a main clause). When doing this, native speakers almost always insert a distinct spoken pause before the weil-clause, essentially treating it like a coordinating conjunction on the fly. However, this colloquial V2 word order is strictly restricted to when the weil-clause follows the main clause. It cannot be used if the weil-clause starts the sentence. Furthermore, it is considered grammatically incorrect in writing and formal speech.

Examples (6)

  1. Ich bleibe zu Hause, weil ich krank bin.

    I am staying at home because I am sick.

    Word by Word: I stay at home, because I sick am.

    Notice how 'bin' (am) moves to the end after 'weil'.

  2. Er lernt Deutsch, weil er in Berlin arbeiten will.

    He is learning German because he wants to work in Berlin.

    Word by Word: He learns German, because he in Berlin work wants.

    In a modal verb construction, the conjugated modal 'will' goes to the end.

  3. Weil es regnet, nehmen wir einen Regenschirm.

    Because it is raining, we are taking an umbrella.

    Word by Word: Because it rains, take we an umbrella.

    When the 'weil' clause comes first, the main clause starts with the verb 'nehmen'.

  4. Ich komme später, weil ich meine Mutter anrufe.

    I am coming later because I am calling my mother.

    Word by Word: I come later, because I my mother at-call.

    With separable verbs, the prefix (an-) and the base verb (rufe) rejoin at the end of the clause.

  5. Warum kommst du nicht? Weil ich müde bin.

    Why aren't you coming? Because I am tired.

    Word by Word: Why come you not? Because I tired am.

    Unlike 'denn', 'weil' can be used as a standalone answer to a Warum? question.

  6. Ich gehe ins Bett, weil ich bin müde.

    I am going to bed because I am tired.

    Word by Word: I go into the bed, because I am tired.

    In casual spoken German, 'weil' is sometimes used with main-clause word order (verb in second position). When doing this, native speakers almost always insert a distinct spoken pause before the 'weil'-clause, essentially treating it like a coordinating conjunction on the fly. This is common in speech but considered incorrect in formal writing. Note that this colloquial V2 order is strictly restricted to when the 'weil'-clause follows the main clause; it cannot be used if the 'weil'-clause starts the sentence.

Common Mistakes

  • Placing the verb in the second position (English word order).

    Ich komme nicht, weil ich habe keine Zeit.
    Ich komme nicht, weil ich keine Zeit habe.

    In written German, the conjugated verb ('habe') must always go to the end of the clause introduced by 'weil'.

  • Forgetting the mandatory comma.

    Sie ist müde weil sie viel arbeitet.
    Sie ist müde, weil sie viel arbeitet.

    German requires a comma to separate a main clause from a subordinate clause.

  • Using 'weil' instead of 'wegen' with a noun phrase.

    Wir bleiben zu Hause weil das Wetter.
    Wir bleiben zu Hause wegen des Wetters.

    'weil' (because) must be followed by a full clause with a subject and a verb. If you want to say 'because of' followed by just a noun phrase, you must use the preposition 'wegen'.

To use 'weil' correctly, you need to understand how German sentences are normally structured so you can identify the 'verb-final' shift. You also need a solid grasp of verb conjugation, as the conjugated verb is the element that moves to the end of the clause.
