English is a West Germanic language that was first spoken in early medieval England and is now a global lingua franca. English is either the official language or one of the official languages in almost 60 sovereign states. It is the most commonly spoken language in the United Kingdom, the United States, Canada, Australia, Ireland, and New Zealand, and is widely spoken in some areas of the Caribbean, Africa, and South Asia. It is the third most common native language in the world, after Mandarin and Spanish. It is the most widely learned second language and an official language of the United Nations, of the European Union, and of many other world and regional international organisations. It is the most widely spoken Germanic language, accounting for at least 70% of speakers of this Indo-European branch. English has developed over the course of more than 1,400 years. The earliest forms of English, a set of Anglo-Frisian dialects brought to Great Britain by Anglo-Saxon settlers in the fifth century, are called Old English. Middle English began in the late 11th century with the Norman conquest of England. Early Modern English began in the late 15th century with the introduction of the printing press to London and the King James Bible, and the start of the Great Vowel Shift. Through the worldwide influence of the British Empire, modern English spread around the world from the 17th to mid-20th centuries. Through all types of printed and electronic media, as well as the emergence of the United States as a global superpower, English has become the leading language of international discourse and the lingua franca in many regions and in professional contexts such as science, navigation, and law. In 1828, Noah Webster created the original Webster's dictionary. Webster's Third is the direct descendant of that great work, and today its unsurpassed quality and reliability carry forward the tradition of innovation and scholarship that started with Noah's original. Merriam-Webster's Third New International was compiled with the utmost accuracy and integrity, drawing on a wealth of editorial resources unique in the publishing industry, including the largest citation collection in the world.
