Imroosian, a language, was spoken by the Imroosian species. On the planet of Vandor, in 10 BBY, the Imroosian Margo used Imroosian to welcome the criminal Tobias Beckett aboard the First Light yacht.
The 2018 film Solo: A Star Wars Story, part of the Anthology Series, marked the initial appearance of Imroosian. Its identification as Imroosian occurred later, in 2019, via the "Star Wars Kids" YouTube video titled "Every Language in Star Wars".
