　　Etymology, the study of words and word roots, may sound like the kind of thing done by boring librarians in small, dusty rooms． Yet etymologists actually have a uniquely interesting job． They are in many ways just like archaeologists （考古学家） digging up the physical history of people and events． The special aspect of etymology is that it digs up history, so to speak, through the words and phrases that are left behind．

　　The English language, in particular,

　　is a great field to explore history through words As a language, English has an extraordinary number of words． This is partly due to its ability to

　　adapt foreign words so readily． For example, " English" words such as kindergarten （from German）, croissant （from French）, and cheetah （from Hindi） have become part of the language with little or no change from their original sounds and spellings． So English-language etymologists have a vast world of words to explore．
