They stay the same but can be combined in different ways like words in a sentence. When you build something you can put patterns together to form a language. So a language for your house might have patterns about transitions, light, ceiling height, connecting the second floor to the ground. A community might put together a language including patterns about public and private spaces, cars, pedestrians and parking. Using languages helps you to visualize and think about what will really make you comfortable, really comfortable.

It's why we enjoy things that are hand made and find mass produced widgets so boring and would like a house that fits just so in the landscape, and like a jewel, brings forth the charm of the landscape itself.
