The Manx Language Week (Cooish) is one of the key events that showcases the language. Held every November the week is a jointly funded by The Heritage Foundation, The Arts Council and Yn Cheshaght Ghailckagh. The week offers a great opportunity for everyone to try and use their Manx. Events are organised that are suitable for both the beginner and fluent speaker. In conjunction with Yn Cheshaght Ghailckagh two lectures, the Ned Maddrell Memorial Lecture and Leaght yn Ghaaue illustrate key developments in the language.
The week culminates in the Kione y Sker award. This award is sponsored by Cains advocates and is given to an individual or organisation whose actions have contributed to Manx as a living language. No festival would be complete with a musical contribution and the Festival has been fortunate to have the support of some extremely talented musicians from the around the Celtic world, not least the Island itself.
