PNEUMONOULTRAMICROSCOPICSILICOVOLCANOCONIOSIS
矽肺病
At 45 letters, this is the longest word you’ll find in a major dictionary. An inflated version of silicosis, this is the full scientific name for a disease that causes inflammation in the lungs owing to the inhalation of very fine silica dust. Despite its inclusion in the dictionary, it’s generally considered superfluous, having been coined simply to claim the title of the longest English word.
