Started in 2001, Wikipedia has rapidly grown into the largest reference website on the Internet. The content of Wikipedia is free, written collaboratively by people from all around the world. This website is a wiki, which means that anyone with access to an Internet-connected computer can edit, correct, or improve information throughout the encyclopedia. There are over 1.15 million articles in English alone.

The next time you're doing a crossword, playing Scrabble (I know, I know, you're not allowed dictionaries here, but every once in a while to check something up you'll need one) don't bother to go through the book version but go on to this fantastic website where you'll find every word and every spelling for every word plus alternatives for every word. American and UK spelling is given in each case. Just click onto this site whenever you need it. It's brilliant!
