concept cloud is a #Wikidata tool that indicates what #Wikipedia articles link to a given Wikipedia article in any and all languages. The idea is that is will help you decide what might be included in a language.
It also allows you to check the labels in your language. Make sure that the spelling is correct and add any missing labels. Quite often you find labels that have not been linked yet. In the screen shot you find items in Nepalese.
Linking them up is part of creating an improved concept cloud. What is really gratifying is when you find halfway that other people are working on merging items as well.
