The Oxford Dictionary Online is a warehouse of over 600,000 words. Despite this large arsenal, they continue to pump some of these new words into their dictionaries to keep them up to date. The world of technology remains a major influence on the English language, with innovative advances reflected in new entries including ethical hacker, 3D printing, and e-learning. Social media also continues to shape language evolution: tweeps, video chat, lifecasting, and hat tip are among the latest words to make their Oxford Dictionary debut, while acronyms regularly used online (from lulz to OH and UX) have also been recognized.
