Rosen Median Language, or RML, is a neography spoken in the Rosen Commonwealth. Devised in 2003 by Teodoro Vidal, Mariane Yamada-Pedroso, and Larissa Delgado, it works as an intermediary working language in the Commonwealth. Based primarily on Sennan, Hanan, and Velese, it is spoken widely within the federal government, and especially the senate, where its use is compulsory. As the Commonwealth is ethno-linguistically diverse, RML was created to “bridge the gap” between speakers of different languages.
