There is a single Mando’a word (primary language spoken by the Mandalorian culture in the Star Wars universe), aay’han, which describes the state of mind when Mandalorians savor a peaceful moment with family and comrades and also grieve for those who’ve died. It is the bittersweet perfect moment of mourning and joy - it is remembering those who are lost or gone, right as you’re celebrating or having the time of your life; it’s about being surrounded by loved ones and enjoying the moment, then suddenly remembering those loved ones that have died.
The nearest basic translation is “bittersweet”, but it hardly comes close to defining what a significant concept it is for Mandalorians. The emotion’s duality is very much in keeping with a people who are a mass of contradictions. [Tsemasi, Star Wars The Old Republic - Daily Life and Death (forum)]
