One of the reasons the verb lassen is so versatile is that it functions very similarly to a modal verb (können, müssen, wollen). However, this means it follows the famous German “Verb Bracket” (Satzklammer) rule.
If you want to say you’re having something done, or letting someone do something, you need to know exactly where to place each piece of the puzzle. Let’s break down the word order for every situation.
1. Basic Word Order (Present Tense)
In a standard main clause, lassen takes the second position and is conjugated to match the subject. The second verb (the action) is “kicked” to the very end of the sentence in its infinitive form.
Formula: [Subject] + [lassen] + [Object] + [Infinitive]
- “Ich lasse (2) mein Auto reparieren (End).”
- “Der Lehrer lässt (2) die Schüler gehen (End).”
2. Word Order in Subordinate Clauses (Weil, Dass, Wenn)
When you use a conjunction like weil or dass, the entire verb group moves to the end. In this case, the conjugated form of lassen stands at the absolute end, right after the infinitive.
- Main Clause: “Ich lasse die Haare schneiden.”
- Subordinate Clause: “…, weil ich die Haare schneiden lasse.”
3. The Tricky Part: The Perfect Tense (Perfekt)
This is where most learners make mistakes. When lassen is used with another infinitive in the past tense, we do not use the Partizip II (gelassen). Instead, we use the Double Infinitive.
- The Rule: Both verbs stay in the infinitive at the end of the sentence.
- Example: “Ich habe mein Auto reparieren lassen.” (Not: reparieren gelassen).

4. Lassen with Modal Verbs
What happens if you want to say “I must have my car repaired”? Now you have three verbs! The modal verb takes the second position, and both lassen and the main action go to the end.
- Formula: [Subject] + [Modal Verb] + [Object] + [Action Infinitive] + [lassen].
- Example: “Ich muss (2) mein Auto reparieren lassen (End).”
This complex structure is common in scenarios involving Passive with Modal Verbs, where verb placement is crucial for the meaning.
5. Summary Table: Where does “Lassen” go?
| Tense / Structure | Position of “Lassen” | End of Sentence |
| Present Tense | Position 2 (Conjugated) | Action Infinitive |
| Subordinate Clause | Absolute End (Conjugated) | Action Infinitive |
| Perfekt (Past) | End (as Infinitive) | Action Infinitive + lassen |
| With Modal Verb | End (as Infinitive) | Action Infinitive + lassen |
💡 Pro Tip for B1/B2 Students
Think of lassen as a magnet. In the present tense, it pushes the other verb to the end. In the past tense or with modal verbs, it gets pulled to the end itself, forming a “verb cluster.”
