All told, approximately 600 words were borrowed from Latin during the Old English period. Often, the Latin word was severely restricted in sense, and was not widespread in use among the general populace. Latin words tended to be literary or scholarly terms and were not very common. The majority of them did not survive into the Middle English Period. Middle Ages The Norman Conquest of 1066 gave England a two-tiered society with an aristocracy which spoke Anglo-Norman and a lower class which spoke English. From 1066 until Henry IV of England ascended the throne in 1399, the royal court of England spoke a Norman language that became progressively Gallicised through contact with French. However, the Norman rulers made no attempt to suppress the English language, apart from not using it at all in their court. In 1204, the Anglo-Normans lost their continental territories in Normandy and became wholly English. By the time Middle English arose as the dominant language in the late 14th century, the Normans had contributed roughly 10,000 words to English of which 75% remain in use today. Continued use of Latin by the Church and centres of learning brought a steady, though dramatically reduced, influx of new Latin lexical borrowings. Renaissance During the English Renaissance, from around 1500–1650, some 10,000 to 12,000 words entered the English lexicon, including the word lexicon. Some examples include aberration, allusion, anachronism, democratic, dexterity, enthusiasm, imaginary, juvenile, pernicious, sophisticated. Many of these words were borrowed directly from Latin, both in its classical and medieval forms. In turn, Late Latin also included borrowings from Greek. Industrial Age The dawn of the age of scientific discovery in the 17th and 18th centuries created the need for new words to describe newfound knowledge. Many words were borrowed from Latin, while others were coined from Latin roots, prefixes, and suffixes, and Latin word elements freely combine with elements from all other languages including native Anglo-Saxon words. Some of the words which entered English at this time are: apparatus,
