You can use a vocabulary list to increase your knowledge of the English language. You can make up a huge list, along with the meanings, and learn one or two new words each day. I'll give you a couple of words to start you off. Pneumonoultramicroscopicsilicovolcanoconiosis would be the longest word and is a lung disease that is caused by the inhalation of very fine silica dust.
. Hepaticocholangiocholecystenterostomies is another long one and means to create a surgical connection between the gall bladder and other organs. If you can learn and spell the two longest words, you'll be way ahead of most people.
