Morish, sometimes called Morš (mɔːrʃ), is an Estvoldian language that originated from regions in and around modern-day Umorej.
The widespread nature of Morish has made it one of the most commonly-spoken languages not only among Estvoldian cultures, but also throughout other planets in the Ealdremen system. Even in areas where Morish holds no legal status as a national language, it is common to learn Morish due to prominent powers that use it as an official language, most notably the Veriol Alliance. Morish's influence on other languages has also been noted throughout history in a phenomenon known as Morish conditioning, where a language linguistically unrelated to Morish begins to display traits such as phonemes or grammar typical of Morish — or loses traits that Morish lacks — after extended contact with Morish speakers. Morish conditioning typically occurs relatively quickly during a long period of occupation or over a long span of time through regular trade and business.
