Pattern Language
Original term: Pattern Language | Chapter/location: 9 to 18 | Chapter start page in the English edition’s table of contents: 157 to 364
Definition and core idea
An organised set of related patterns that can formulate solutions to recurring design problems.
Explanation and elaboration
The analogy with natural language stresses combinability: patterns provide shared rules and vocabulary, but their relations and order also matter. The “genetic code” metaphor points to the language’s generative capacity; it is not an exact scientific equivalence with biological DNA.
Notes and limits of interpretation
Caution in attribution
The Timeless Way sets out the theoretical foundations; A Pattern Language presents a detailed, applied collection of patterns. The two are related but are not a single work.
