ref: lddd - ubiquitous language a ubiquitous language is not “ubiquitous” in the sense that it should be used and applied “ubiquitous” 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.
