Ubiquitous language is a model that acts as a universal language to help communication between software developers and domain experts.

Ubiquitous Language is the term Eric Evans uses in Domain Driven Design for the practice of building up a common, rigorous language between developers and users.

Domain-driven design is a software design approach focusing on modelling software to match a domain according to input from that domain's experts. In terms of object-oriented programming it means that the structure and language of software code should match the business domain.
