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.
Speaker counts are approximate orders of magnitude for learners, not census figures. Family labels follow Glottolog-style classification; vitality notes (when shown) follow UNESCO WAL / Ethnologue-style framing and should be re-checked for program planning.
