How to Express 'As If' in German: Mastering 'als ob' with Konjunktiv II

Have you ever watched someone behave with exaggerated confidence and thought, "He acts as if he owns the place"? Or perhaps you stepped outside on an overcast July morning in Berlin and muttered, "It looks as though it might snow"? Comparing a real situation to an imaginary or hypothetical scenario is something we do constantly in conversation. In German grammar, this concept is known as an irrealer Vergleichssatz (unreal/hypothetical comparative clause).

To express "as if" or "as though" in German, you primarily use the conjunction als ob combined with the subjunctive mood, Konjunktiv II. While the structure might look intimidating at first glance, it follows predictable grammatical patterns once you understand how clause structure and subjunctive forms interact.

In this comprehensive guide, we will break down how to construct sentences with als ob, explore stylistic alternatives like als wenn and shortened als constructions, review the necessary Konjunktiv II forms, and highlight the most common traps learners face when putting these structures into practice.

1. What Are Hypothetical Comparative Clauses?

A hypothetical comparative clause compares an existing reality to an unreal or counterfactual condition. In German, these clauses answer the implicit question: "How does something appear, feel, sound, or seem?"

These clauses frequently follow trigger verbs and expressions such as:

• tun so (to act / pretend): Er tut so... (He acts...)
• aussehen (to look like): Es sieht so aus... (It looks like...)
• sich anhören / klingen (to sound like): Das klingt so... (That sounds like...)
• sich anfühlen (to feel like): Es fühlt sich so an... (It feels like...)
• den Eindruck machen (to give the impression): Sie macht den Eindruck... (She gives the impression...)

Because the comparison refers to something that is contrary to fact or purely imaginary, standard German grammar pairs these clauses with the Konjunktiv II (the subjunctive mood used for hypothetical situations and wishes), as documented in standard references like Wikipedia's overview of German Konjunktiv II.

2. The Standard Structure: 'als ob' + Subordinate Clause

The most common and universally accepted way to say "as if" in German is with the conjunction als ob.

Grammatically, als ob introduces a subordinate clause (Nebensatz). Just like subordinate clauses starting with weil or dass, the conjugated verb must move to the very end of the clause. (If you want a refresher on subordinate word order, check out our guide on German causal conjunctions like weil, denn, and da).

Basic Sentence Formula:

[Main Clause] + , + als ob + [Subject] + [Other Elements] + [Konjunktiv II Verb]

Examples with Present Situations:

• Er spricht so leise, als ob er ein Geheimnis hätte.
  (He speaks so quietly, as if he had a secret.)
• Du tust so, als ob du mich nicht verstehen würdest.
  (You act as if you didn't understand me.)
• Sie sieht aus, als ob sie müde wäre.
  (She looks as if she were tired.)

Notice that the main clause often includes the particle so (e.g., Er tut so..., Es klingt so...), which acts as a bridge pointing forward to the hypothetical comparison.

3. Essential Konjunktiv II Forms for 'als ob'

To use als ob smoothly, you need a quick recall of Konjunktiv II verb forms. In modern spoken and written German, Konjunktiv II falls into two main categories: synthetic (one-word) forms and analytical (two-word) forms with würde.

A. High-Frequency One-Word Forms

For auxiliary verbs, common strong verbs, and modal verbs, native speakers virtually always use the one-word Konjunktiv II form:

• sein → wäre, wärest, wäre, wären, wärt, wären
• haben → hätte, hättest, hätte, hätten, hättet, hätten
• wissen → wüsste, wüsstest, wüsste, wüssten, wüsstet, wüssten
• brauchen → bräuchte, bräuchtest, bräuchte, bräuchten, bräuchtet, bräuchten

B. Modal Verbs in Konjunktiv II

When hypothetical comparisons involve ability, permission, or obligation, use the Konjunktiv II forms of modal verbs (with umlauts where applicable):

• können → könnte
• müssen → müsste
• dürfen → dürfte
• sollen → sollte

Example: Er benimmt sich, als ob er alles dürfte. (He behaves as if he were allowed to do anything.) For a detailed look at modal verb conjugations, read our German modal verbs guide.

C. The 'würde' + Infinitive Construction

For most regular (weak) and many irregular verbs, forming the original Konjunktiv II looks identical to the simple past (Präteritum), or sounds archaic. Therefore, modern German uses würde + Infinitive:

• Sie schaut mich an, als ob sie mich schlagen würde. (She looks at me as if she were going to hit me.)
• Er redet, als ob er in Berlin wohnen würde. (He talks as if he lived in Berlin.)

D. Expressing Past Events (Konjunktiv II Past)

If the hypothetical comparison refers to an event in the past, construct the past Konjunktiv II using hätte or wäre + Partizip II (Past Participle):

• Sie tut so, als ob sie die Prüfung bestanden hätte.
  (She acts as if she had passed the exam — but in reality, she failed or hasn't taken it.)
• Er sieht aus, als ob er die ganze Nacht gelaufen wäre.
  (He looks as if he had run all night.)

4. Two Common Variations: 'als wenn' and 'als' + Inverted Word Order

While als ob is the default construction taught in textbooks, you will regularly encounter two other variations in both conversational and literary German.

Variation 1: 'als wenn'

als wenn is completely synonymous with als ob. It follows identical subordinate word order (verb at the end). It is common in spoken German and literature, though als ob is slightly more standard in professional and formal writing.

• Es riecht, als wenn jemand Kuchen gebacken hätte.
  (It smells as if someone had baked a cake.)

Variation 2: 'als' + Inverted Verb Order (Verb-Second)

This is where many learners stumble. When you omit ob or wenn and use als alone to express "as if", the clause changes from subordinate word order to verb-second (V2) word order. The conjugated Konjunktiv II verb immediately follows als.

Let's compare the two structures side by side:

The als + [verb] construction sounds very elegant and natural in everyday German conversation. Pay special attention to the subject pronoun, which shifts directly behind the verb:

• Der Hund schaut, als hätte er tagelang nichts gefressen.
  (The dog looks as if he hadn't eaten anything for days.)
• Sie antwortete, als wisse/wüsste sie nichts von dem Vorfall.
  (She answered as if she knew nothing about the incident.)

5. Konjunktiv II vs. Konjunktiv I vs. Indicative (Real vs. Unreal)

Grammar enthusiasts and advanced students preparing for B2 or C1 exams often ask: Do we ever use Konjunktiv I or the Indicative (normal present tense) with 'als ob'?

A. Konjunktiv II (Standard Unreal Comparison)

Used when the speaker wants to emphasize that the statement is strictly counterfactual or unlikely.

• Er tut so, als ob er reich wäre. (He acts as if he were rich — implication: he is definitely not rich).

B. Konjunktiv I (Formal / Journalistic Style)

In formal written German and news media, Konjunktiv I is sometimes used in comparative clauses to report an appearance without confirming or denying its truth:

• Der Angeklagte verhält sich, als sei er unschuldig. (The defendant acts as if he were innocent — neutral reporting).

C. Indicative (Spoken Everyday German)

In casual colloquial speech, native German speakers sometimes use the normal indicative mood instead of Konjunktiv II:

• Er tut so, als ob er mich nicht kennt. (Casual speech)

While understood, using the indicative in written exams or formal essays is considered bad style. Sticking to Konjunktiv II ensures your sentences are grammatically precise.

If you are practicing persuasive writing or structured discussions for tests like TestDaF or Goethe-Zertifikat, expressing nuance through precise grammar is critical. Explore our article on phrases for expressing your opinion in German to strengthen your argumentation skills.

6. Common Mistakes to Avoid

When mastering hypothetical clauses with als ob, keep an eye out for these frequent errors:

1. Putting the verb in position 2 with 'als ob':
   Incorrect: *Er tut so, als ob er ist mein Freund.
   Correct: Er tut so, als ob er mein Freund wäre.
2. Putting the verb at the end with 'als' alone:
   Incorrect: *Er tut so, als er mein Freund wäre.
   Correct: Er tut so, als wäre er mein Freund.
3. Forgetting the umlaut on modal verbs in Konjunktiv II:
   Incorrect: *Sie tut so, als ob sie kein Deutsch konnte (Past tense: could).
   Correct: Sie tut so, als ob sie kein Deutsch könnte (Konjunktiv II: could / were able to).
4. Omitting the comma: In German, subordinate and comparative clauses must always be separated from the main clause by a comma.

7. Putting It into Practice with Real Dialogues

Here are two typical daily scenarios illustrating how native speakers naturally use these structures in Germany.

Scenario A: At the Office (Am Arbeitsplatz)

Lukas: Warum arbeitet Markus heute so hektisch?
Sarah: Keine Ahnung. Er tut so, als ob das gesamte Projekt heute noch fertig werden müsste.
Lukas: Stimmt. Er rennt durch den Flur, als brenne das Büro!

Scenario B: Discussing the Weather (Über das Wetter sprechen)

Anna: Nimm lieber eine Jacke mit.
Ben: Warum? Der Himmel ist doch blau.
Anna: Ja, aber der Wind fühlt sich so an, als käme bald ein Unwetter.

Summary Checklist for 'als ob'

• Use als ob or als wenn when you want the verb at the end of the clause: ..., als ob er krank wäre.
• Use als alone when you want the verb in the second position: ..., als wäre er krank.
• Pair these constructions with Konjunktiv II (wäre, hätte, könnte, würde + Infinitiv) to indicate unreality.
• Use hätte/wäre + Partizip II to compare an unreal event in the past.
• Always place a comma before the comparative clause.

With these simple rules and patterns in your toolkit, expressing hypothetical comparisons in German will quickly feel second nature. Try writing down three observations about your surroundings today using als ob and als + V2 to solidify your understanding!
