To invent is to create for the first time or make up. If you tell your friends that you invented the electric guitar, you are inventing a pretty unbelievable story about your past.
When you think of the word invent, think of Thomas Alva Edison who invented the long-lasting light bulb, the motion picture camera, the phonograph, and the stock ticker. That's a lot of inventions! You couldn't invent a better story of American ingenuity, could you?
