Prove him wrong, guys
Who in the world came up with this post? The only double-O letter in the English language is “Good?” You can Google double-O words and find that there are 6,183 words in the dictionary. In fact, Google is recognized as a real word in the English language, so you only have 6,182 words to find.
But the commenter to this post really set the OP straight. “Book. Try reading one.” Books open us up to all kinds of worlds, both fictional and real, by conveying images through word form. You can also learn a lot of new vocabulary if you pick up a book once in a while.
