Abstract:

Technology changes the way we live. It also affects the way we speak. As the gadgets we make and use grow more complex, we’re sneaking in complexities into the words we use too. Like ‘printed book’. What was always called just a ‘book’ (hard cover or paperback) is now called a printed book, simply because now we have e-books. What was once simply a guitar is now an acoustic guitar, because of the growing popularity of electric guitars.
