The Cooish is the name of a festival similar to the traditional Welsh Eisteddfod that promotes Manx language, it's literature, and culture that takes place on the Isle of Man each November.

[5] By gaining support from local businesses and the Manx government, as well as employing extensive advertising, the festival has been able to "ensure that most people in the country are aware of the language.

[8] The Cooish is organised by Yn Çheshaght Ghailckagh with support from the Manx Heritage Foundation and the Isle of Man Arts Councils along with local businesses.

[11] There are language workshops to help people who are interested in learning or improving their Manx, as well as general information sessions for parents to discuss the advantages of bilingualism and of sending their child to the Bunscoill Ghaelgagh or Mooinjer Veggey.

[12] Although the primary purpose of the Cooish is to promote the Manx language, it aims to bring together different elements of the Gaelic world to celebrate their shared heritage.
