ciekawego
"Ciekawego" means "interesting" or "something interesting" in English.
The word 'ciekawego' is used here in the masculine singular form, as it refers to 'coś' (something), which is treated as masculine in Polish.
Czy masz coś ciekawego do powiedzenia?
Do you have anything interesting to say?
In this example, 'ciekawego' describes 'coś' (something) that the speaker saw, implying a characteristic or quality.

Here, 'ciekawego' again modifies 'coś' (something), central to requesting an engaging or intriguing detail.
