Questions & Answers about Wir passen den Plan an.

Why are passen and an split in Wir passen den Plan an? Isn’t it one verb?

In German, anpassen is a separable prefix verb.

• The base verb is passen.
• The prefix is an-.
• In main clauses with normal word order, the finite verb (the part that is conjugated) goes in second position, and the prefix moves to the end of the clause.

So:

• Dictionary form: anpassen = to adjust / to adapt (something)
• Present tense, main clause: Wir passen den Plan an.
  (passen in 2nd position, an at the end)

This is a normal behavior for separable verbs like:

• aufstehen → Ich stehe früh auf. (I get up early.)
• mitkommen → Kommst du mit? (Are you coming along?)

What is the difference between passen and anpassen?

They have related but different meanings:

• passen (without prefix) usually means:

  • to fit (size, shape):
    Der Pullover passt. – The sweater fits.
  • to suit (be convenient/appropriate):
    Der Termin passt mir. – The appointment suits me / works for me.

• anpassen (with an-) means:

  • to adjust, adapt, modify something so it fits a situation or requirement.

In Wir passen den Plan an., you are modifying the plan, not just saying it fits.

Why is it den Plan and not der Plan or dem Plan?

Plan is a masculine noun in German:

• Nominative (subject): der Plan
• Accusative (direct object): den Plan
• Dative (indirect object): dem Plan
• Genitive: des Plans

In Wir passen den Plan an.:

• Wir = subject (nominative)
• den Plan = direct object (accusative)

Since Plan is the thing being adjusted, it must be in the accusative, so the article becomes den.

How do I know that Plan is masculine?

You generally have to learn the gender with the noun:

• der Plan (masculine)
• die Idee (feminine)
• das Projekt (neuter)

Dictionaries usually show the gender with m. / f. / n. or with the article:

• der Plan, Pläne (m.)

Once you know Plan is masculine (der Plan), you can then decline it correctly:

• Nominative: der Plan
• Accusative: den Plan
• Dative: dem Plan

Why is Plan capitalized?

In German, all nouns are capitalized, regardless of where they appear in the sentence.

So you write:

• der Plan
• ein Auto
• die Idee
• Wir passen den Plan an.

Even in the middle of a sentence, Plan must start with a capital letter because it is a noun.

Where does the an go in other tenses or sentence types?

The position of an changes with clause type and tense:

1. Simple main clause (present/future with werden)

   • Present: Wir passen den Plan an.
   • Future: Wir werden den Plan anpassen.
     (the full verb anpassen is at the end with werden)

2. Perfect tense (with haben)

   • Wir haben den Plan angepasst.
     The prefix an- attaches to the participle: angepasst, which goes to the end.

3. Subordinate clause (introduced by a conjunction like weil, dass, wenn)
   The verb goes to the very end in its full form (not separated):

   • …, weil wir den Plan anpassen.
   • …, dass wir den Plan anpassen.

4. Yes–no question (verb first):

   • Passen wir den Plan an?

5. Imperative (command):

   • Pass den Plan an! (du)
   • Passt den Plan an! (ihr)
   • Passen Sie den Plan an! (Sie – formal)

Could the sentence also be reflexive, like Wir passen uns an? What is the difference?

Yes, anpassen can be:

1. Reflexive: sich anpassen = to adapt oneself

   • Wir passen uns an. – We adapt (ourselves).
     Often followed by an + Akkusativ:
   • Wir passen uns an die neue Situation an. – We adapt to the new situation.

2. Non-reflexive: etwas anpassen = to adapt/adjust something

   • Wir passen den Plan an. – We adjust the plan.
   • Wir passen den Plan an die neue Situation an. – We adapt the plan to the new situation.

So:

• Wir passen uns an. → We change ourselves.
• Wir passen den Plan an. → We change the plan.

Is Wir passen den Plan an. the same as Wir ändern den Plan.?

They are similar, but not identical in nuance:

• ändern = to change (more general)
  • Wir ändern den Plan. – We change the plan.
• anpassen = to adjust/adapt (usually to fit requirements, conditions, or a new situation)
  • Wir passen den Plan an. – We adjust the plan (so it fits something).

Often, anpassen implies change with a goal of better fit:

• Wir passen den Plan an die neuen Anforderungen an.
  We adapt the plan to the new requirements.

Can I leave out den Plan and just say Wir passen an?

Normally, no. In the meaning to adjust something, anpassen almost always needs a direct object:

• Wir passen den Plan an. – We adjust the plan.
• Wir passen die Strategie an. – We adjust the strategy.

If you say Wir passen an. by itself, it sounds incomplete or very colloquial/context-dependent, and will usually make people ask: What are you adjusting?

If you want to say We (ourselves) adapt, then you must use the reflexive form:

• Wir passen uns an. – We adapt (ourselves).

How would I replace den Plan with a pronoun?

If the context already makes clear what den Plan is, you can replace it with a pronoun:

• Wir passen ihn an. – We adjust it.

Key points:

• ihn is the accusative pronoun for a masculine object (replacing den Plan).
• In a simple main clause, the separable prefix an still goes to the end:
  • Wir passen ihn an.

If you include another phrase, it still stays at the end:

• Wir passen ihn an die neue Situation an.
  (We adjust it to the new situation.)

Why isn’t it Wir passen den Plan an etwas instead of an at the very end?

If you add what you adjust the plan to, you actually get two things with an:

• Wir passen den Plan an die neue Situation an.

Structure:

• Wir – subject
• passen – conjugated verb (2nd position)
• den Plan – direct object
• an die neue Situation – prepositional phrase (to the new situation)
• an – separable prefix at the end

The first an belongs to the preposition an die neue Situation.
The last an is the separable prefix of anpassen that must go to the end in a main clause.

You cannot combine them into one; they have different grammatical roles.

How would I say We adjusted the plan (past tense) using the same verb?

Using the perfect tense with haben and the past participle angepasst:

• Wir haben den Plan angepasst. – We have adjusted the plan / We adjusted the plan.

Notes:

• The past participle of anpassen is angepasst (prefix re-attaches).
• In the perfect tense:
  • haben is conjugated and goes in 2nd position.
  • angepasst goes to the end of the clause.
