Klingon (tlhIngan Hol) is the constructed language developed for Star Trek and expanded by Marc Okrand. It has an unusually complete learner ecosystem for a fictional language — including a Duolingo course and the Klingon Language Institute. Treat it as a fun, structured conlang project; pronunciation and unusual word order take deliberate practice.

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.
