Carino/cute/kawai
I'm Italian, beginner, my gf she's Italian/Polish of second generation.
She's used to speak Polish only in her family so we are missing out a lot of slang.
In Italian we used this word "carino!" In the same way that a Japanese would say kawaii. It's something you can say for a puppy, but also for a man which is doing something nice in a gentle way.
Is there a way to say it in Polish?
