However, here are some options depending on the context:
If referring to the specific holiday:
* Dzień Dziękczynienia: This is the most literal translation, literally "Day of Thanksgiving," but it's not commonly used in Poland.
* Amerykańskie Święto Dziękczynienia: This means "American Thanksgiving" and is the most accurate way to refer to the holiday.
If referring to the act of expressing gratitude:
* Dzień wdzięczności: This means "Day of Gratitude," and it could be used in a broader sense to refer to expressing gratitude.
* Święto Dziękczynienia: This means "Festival of Thanksgiving" and is more poetic and less specific to the American holiday.
* Wyrażanie wdzięczności: This literally means "Expressing gratitude" and can be used for any occasion where you are thanking someone.
Ultimately, the best way to say "Thanksgiving" in Polish will depend on the specific context and what you're trying to convey.
