How does sign language let people talk with their hands?

Picture a whole conversation happening in total silence — no sound at all, yet two people are laughing, arguing, telling stories, even cracking jokes. How? Their hands are doing the talking. This is sign language, and it's a real, full language built out of movement instead of noise.
Here's the first surprise: sign language isn't just spelling words in the air with finger shapes. It's a complete language with its own grammar — its own rules for how to put ideas together — just like spoken languages have. The hands carry the words, but a lot more than the hands is working.
