Here's how the English language got started. After Roman troops withdrew from Britain in the early 5th century, three Germanic peoples — the Angles, Saxons, and Jutes — moved in and established kingdoms. They brought with them the Anglo-Saxon language, which combined with some Celtic and Latin words to create Old English. Old English was first spoken in the 5th century, and it looks incomprehensible to today's English-speakers. To give you an idea of just how different it was, the language the Angles brought with them had three genders (masculine, feminine, and neutral). Still, though the gender of nouns has fallen away in English, 4,500 Anglo-Saxon words survive today. They make up only about 1 percent of the comprehensive Oxford English Dictionary, but nearly all of the most commonly used words that are the backbone of English. They include nouns like "day" and "year," body parts such as "chest," arm," and "heart," and some of the most basic verbs: "eat," "kiss," "love," "think," "become." FDR's sentence "The only thing we have to fear is fear itself" uses only words of Anglo-Saxon origin.
