The aim of the Webster's American Family Dictionary is unique and challenging: it is to capture and record the standard vocabulary of American English in a way that reflects the common ethical, moral, religious, social, and civic values of mainstream Americans. It is, in short, both a lexical and cultural record of standard American English at the dawn of the 21st century.
