Lifeworld (or life-world) (German: Lebenswelt) may be conceived as a universe of what is self-evident or given, a world that persons may experience together. The concept was popularized by the German philosopher Edmund Husserl, who emphasized its role as the ground of all knowledge in lived experience.

In contemporary society the knowledge variety that is acted with in work systems is evident from the wide range of products and services covered by the Central Product Classification v. 2.1.

Jürgen Habermas has further developed the concept of the lifeworld in his social theory. For Habermas, the lifeworld is more or less the "background" environment of competences, practices, and attitudes representable in terms of one's cognitive horizon. Habermas, whose social theory is grounded in communication, focuses on the lifeworld as consisting of socially and culturally sedimented linguistic meanings. It is the lived realm of informal, culturally-grounded understandings and mutual accommodations.
