Because of and thanks to (yüzünden, sayesinde)

When evaluating an outcome—like dissecting a team's performance after an intense escape room—Turkish uses two distinct words to separate positive credit from negative blame.

Positive Attribution: sayesinde

To express "thanks to," use the postposition sayesinde. It is used strictly for positive outcomes where you want to give credit.

Thanks to his intelligence, we finished the escape game.
Onun zekâsı sayesinde kaçış oyununu bitirdik.

Grammatically, sayesinde follows a word in the genitive case. When crediting a specific trait, the person or group takes the genitive suffix (the "possessor"), and their helpful trait takes the possessive suffix.

Thanks to the team's cooperation, we won the game.
Takımın işbirliği sayesinde oyunu kazandık.

Negative Cause: yüzünden

To express "because of" in a negative sense—when assigning blame or explaining a failure—use yüzünden.

Because of your impatience, we lost the game.
Senin sabırsızlığın yüzünden oyunu kaybettik.

It works exactly like sayesinde grammatically, but strictly carries a tone of fault or regret.

Because of their mistake, the door did not open.
Onların hatası yüzünden kapı açılmadı.

Blaming or Crediting Directly

If you want to attribute the outcome directly to a specific person or group rather than a trait, simply attach the genitive suffix directly to that person or group, immediately followed by the postposition.

Because of the players who argued, we lost time.
Kavga eden oyuncuların yüzünden zaman kaybettik.

Contrasting Outcomes

In a post-game analysis, you can easily pair both structures in a single sentence to break down a mixed performance:

We solved the problem thanks to your intelligence, but we lost time because of his carelessness.
Senin zekân sayesinde problemi çözdük ama onun dikkatsizliği yüzünden zaman kaybettik.
