Try reading the longest word in English, "pneumonoultramicroscopicsilicovolcanoconiosis". Did you succeed? Even a song of this word has been sung. What do you think this word is used to express and by whom was it sung? Let's know :)
It's a lung disease. It is said to have been sung by Kagamine Len and Dasu. However, I haven't heard it yet. I'm very curious how you pronounce it in the song because I can never sing it all at once :))
