The verb „lassen" (Lass das!)

Overview: The many meanings of lassen

• Lass uns + Infinitiv → making a suggestion together.
• Lass …! → telling someone to stop something (imperative).
• jemanden / etwas + lassen → leaving something or someone as they are / where they are.
• lassen + nominalised verb → stopping a habit.

Focus on these four uses. Do not try to learn every possible meaning of lassen at once.

1. Suggestions with Lass uns + Infinitiv

Use this when you want to say “Let’s …”.

• Formula: Lass + uns + … + Infinitiv (at the end)

Important word order:

• uns is always directly after Lass.
  Lass morgen wir in den Zoo gehen.
  ✅ Lass uns morgen in den Zoo gehen.
• The main verb (Infinitiv) stands at the end of the sentence.

Self-check:

1. Do I have Lass uns together at the start?
2. Is the main verb in the infinitive at the end?
3. Does the sentence really express a suggestion we do together?

2. Imperative: telling someone to stop (Lass …!)

Here, lassen is an order: “Stop that”, “Leave it”, “Don’t do that”.

• Formula (du-form): Lass + Objekt …

Politeness tips:

• Add bitte to sound softer: Lass das bitte!
• Still, this is a clear order. It can sound direct or annoyed.

Common confusion:

• Lass das! → “Stop doing this.”
• Lass die Kinder Angst haben. → “Let the children be afraid.” (allow it)

So for “Stop that, the children are afraid”, you need Lass das, not Lass die Kinder Angst haben.

Self-check:

1. Am I telling someone to stop an action? → Use Lass + das / mich / ihn …
2. Is it about allowing something? → That is a different meaning of lassen (not the focus here).

3. Leaving something as it is: jemanden / etwas + lassen

Use this when you do not change something, or you leave something somewhere.

• Formula: Subjekt + lässt / lassen + Objekt + (Ort) + Infinitiv

Word order pattern:

• The object comes before the infinitive:
  ✅ Wir lassen das Auto auf dem Parkplatz stehen.
  Wir lassen stehen das Auto auf dem Parkplatz.

Meaning check:

• Often you can translate with “leave”:
  – “leave the car (where it is)”
  – “leave my bag (in the office)”

Self-check:

1. Is there an object after lassen (Auto, Tasche, die Kinder …)?
2. Do I want to say “leave it there / as it is”? → then this structure fits.
3. Is the extra verb (stehen, liegen, spielen) at the end?

4. Stopping a habit: lassen + nominalised verb

Here you say that you want to stop a habit or behaviour.

• Formula: Subjekt + lassen + das + Verb (with capital letter)
• This “Verb with capital” is a nominalised verb (it becomes a noun).

Capital letter is important:

• das Rauchen, das Trinken, das Arbeiten → nouns.
• This is why they take an article das.

Do not confuse:

• Ich lasse das Arbeiten. → I stop working (I am not working now).
• Ich lasse heute arbeiten. → I let other people work today (e.g. I am the boss).

Self-check:

1. Do I mean “stop a habit”? (smoking, drinking, arguing…)
2. Do I have das + Verb with capital?
3. Can I translate with “stop …-ing” in English? If yes, this structure is probably correct.

5. Mini decision guide: which lassen do I need?

Use these quick questions to choose the right pattern.

1. Do I want to say “Let’s …” (we do something together)?
   → Use Lass uns + Infinitiv.
   Lass uns morgen in den Zoo gehen.
2. Do I want to tell someone to stop something now?
   → Use Lass …! (imperative).
   Lass das bitte! Lass mich in Ruhe!
3. Do I want to say “leave something / someone (as they are / where they are)”?
   → Use jemanden / etwas + lassen (+ Verb at the end).
   Wir lassen das Auto auf dem Parkplatz stehen.
4. Do I want to say “stop a habit / behaviour”?
   → Use lassen + das + Verb (capital).
   Ich lasse das Rauchen.

6. Short practice: check yourself

For each English sentence, think of the German pattern you need. You do not have to write full answers here, just choose the correct type.

1. “Let’s have lunch in the park.”
   → Pattern? Lass uns + Infinitiv
2. “Please stop this discussion now.”
   → Pattern? Lass …! (imperative)
3. “We will leave the laptops in the office.”
   → Pattern? etwas + lassen (leave something somewhere)
4. “I want to stop eating sugar.”
   → Pattern? lassen + das + Verb (capital)

If you can choose the correct pattern for these four, you have understood the core of this unit.

7. What to pay attention to (summary)

• Meaning first: suggestion, order to stop, leave something, or stop a habit?
• Word order:
  • Lass uns always together.
  • Infinitives at the end of the sentence.
  • Object before infinitive: lassen das Auto stehen.
• Capital letter with habits: das Rauchen, das Trinken.
• Politeness: add bitte to Lass …, but remember it is still direct.

Re-read the examples and check: Can I see which type of lassen it is? If yes, you are ready to use this in conversation.
