In which different languages can you say “welcome”. If you have a device you could research “welcome” in different languages and try saying welcome, those whom you gather with can try to guess the language. Here are a few to try: Bienvenidas = Spanish Velkommen = Danish Gratissimum = Latin добро пожаловать = Russian Welina = Hawaiian ようこそ (Yōkoso) = Japanese. What about sign language?
