Lojban is a carefully engineered logical language based on predicate logic, designed for unambiguous expression. It is an original constructed language (not fiction IP) with a complete baseline grammar, a finite root vocabulary (gismu), and long-running community tools. Expect a steeper conceptual curve than Esperanto — rewarding if you like grammar systems.
