Bounded contexts allow us to complete the definition of a ubiquitous language. A ubiquitous language is not “ubiquitous” in the sense that it should be used and applied “ubiquitously” throughout the organization. A ubiquitous language is not universal.

Instead, a ubiquitous language is ubiquitous only in the boundaries of its bounded context. The language is focused on describing only the model that is encompassed by the bounded context. As a model cannot exist without a problem it is supposed to address, a ubiquitous language cannot be defined or used without an explicit context of its applicability.
