Improving your vocabulary can be done at any age and any level of  education. Even college students can benefit from an enlarged  vocabulary, which will enhance spoken and written communication as well  as providing a deeper grasp of any language. Often people are spurred to  improve their vocabularies by a major test, but improving your  vocabulary can be done for fun as well. There are a variety of ways to  improve your vocabulary, most of which are interactive and easy. 
One of the best ways to improve your vocabulary is to read  more. Reading is clearly linked with a larger vocabulary, especially if  you seek out books in unfamiliar genres or about unfamiliar topics. Nonfiction in a wide variety of fields can improve your vocabulary and general knowledge. Literacy in fiction is also highly beneficial. As you read, make a note of unfamiliar words, look them up, and write down the definition.
                       
			            Another way to improve your vocabulary is to play word games. Games like Scrabble and Boggle will encourage your brain to play with words and letters, as well as learning new ones. If you play Scrabble with an open dictionary,  you can encourage people to try out words they might otherwise be  afraid of using. Most word games are interactive, so you enjoy company  while you improve your vocabulary.
Another way of improving your vocabulary is to do word puzzles. Most  newspapers include crosswords, simple cryptology puzzles, and jumbles  which get progressively harder throughout the week. Improve your  vocabulary by trying to commit to completing all of the word puzzles  every day. Word puzzles can also be done in groups, especially if you  enjoy competition. You can also purchase books of word puzzles of  varying difficulty.
			                  A simple way to improve your vocabulary is to use the dictionary. Create  flash cards of unfamiliar words and practice them in the train, on the  bus, or when you wake up in the morning. Try to practice words in a  variety of environments so that you really learn them, and make sure to  use the words in daily sentences as well so that you can grow accustomed  to using them correctly.
In addition, you may find a community of individuals with interests like yours. If you are trying to improve your English  vocabulary as a native speaker, you may be able to meet up with study  buddies. If you are learning vocabulary in a new language, you can find  people to speak and write with you so that you can improve your skills.
