Here are some options:
* "Kraanberi" (క్రాన్బెర్రీ): This is the transliteration of the English word, which is widely understood in Telugu-speaking regions.
* "Aalu" (ఆలు): This is the general Telugu word for "berry." You could use this with a qualifier like "Kraanberi aalu" (క్రాన్బెర్రీ ఆలు) to mean "cranberry."
* "Sambaar kaayi" (సాంబార్ కాయ్): This literally means "sambar fruit," and while it is usually used for tamarind, it could be used colloquially for cranberry if it is used in a similar way (e.g., for making jams or sauces).
Ultimately, the best way to convey "cranberry" in Telugu would be to use the transliteration "Kraanberi" or a descriptive phrase like "Kraanberi aalu."
