X-bar is a linguistic theory about the structure of syntax in human languages. This theory, and most other modern theories of syntax, organize sentences and phrases into hierarchical tree structures.
The same type of hierarchical structure is used in Xholon. The following figure shows one of several Xholon models that explore the similarities of hierarchical structure in Xholon, and in X-bar and related linguistic theories.
