✦Grammar Breakdown
DankefürdeineZusammenarbeit.
Danke
Used as an interjection meaning 'thank you'; it can stand alone or be followed by a prepositional phrase.
für + Accusative
The preposition 'für' always governs the accusative case; the noun phrase after it must be in accusative.
deine (possessive determiner)
‘deine’ is the feminine accusative form of the possessive determiner ‘dein’ (your). It agrees with the feminine noun ‘Zusammenarbeit’.
Zusammenarbeit (feminine noun)
‘Zusammenarbeit’ means ‘cooperation’; it is a feminine noun, so its accusative form is identical to the nominative.
🗨In Conversation
Danke für deine Zusammenarbeit.
Thank you for your cooperation.
Gern geschehen, ich freue mich auf die nächsten Schritte.
You're welcome, I look forward to the next steps.
✕Common Mistakes
Danke für dein Zusammenarbeit.
‘dein’ is masculine/neuter accusative; the noun ‘Zusammenarbeit’ is feminine, so the correct form is ‘deine’.
Für deine Zusammenarbeit.
Leaving out ‘Danke’ makes the sentence sound incomplete; you need a gratitude expression before the prepositional phrase.
Danke für deine Zusammenarbeit.
In very formal contexts you should use the polite ‘Ihre’ instead of ‘deine’.
↔Alternatives
Vielen Dank für deine Mitarbeit.
Many thanks for your contribution.
Ich danke dir für deine Unterstützung.
I thank you for your support.
Danke für die gute Zusammenarbeit.
Thanks for the good cooperation.
Cultural Tip
In German business communication, expressing gratitude is expected and helps maintain a positive working relationship. ‘Zusammenarbeit’ sounds more formal than ‘Mitarbeit’, so choose it when you want to keep a professional tone. In very formal letters you would replace ‘deine’ with the polite ‘Ihre’ (e.g., ‘Danke für Ihre Zusammenarbeit’).
